-->-- '''Jennifer''', ''Jennifer's Body''

Pre-menstrual syndrome ([=PMS=]) refers to the physical and mental effects of hormone changes in females of childbearing years. Those effects can include depression, tender breasts, food cravings, bloating, fatigue, mood swings, constipation or diarrhea, and irritability. The Mayo Clinic [[http://www.mayoclinic.com/health/premenstrual-syndrome/DS00134 estimates]] that three out of four women between puberty and menopause will have some form of [=PMS=].

If a fictional work decides to avert NoPeriodsPeriod, though, forget about the 25% who don't suffer any ill effects. The only effect of [=PMS=] will be irritability, and ''every'' menstruating woman ''will'' suffer from it.

Occasionally, a work will use a different effect of [=PMS=]. However, the only significance of these will be to ''make'' the character irritable. Cramps are good for this, especially considering that 3-7 days of pain will make just about anyone cranky. Bloating might show up so the character can complain about her clothes not fitting. You won't see [[WackyCravings food cravings]], though, as they're associated with pregnancy -- unless the writers are trying to [[MistakenForPregnant throw a curveball]].

For the supernatural version, see MenstrualMenace.

[[folder: Anime And Manga ]]

* Averted in ''Manga/SeitokaiYakuindomo''. Though the girls [[AvertedTrope do complain]] about menstrual cramps, their personalities seem unaffected.
* Played to good effect in the ''GunslingerGirl'' anime when Triela suffers from her period. She has intense cramps and implied nausea, made worse by the fact that she is forbidden pain killers by the Agency because of her conditioning. The irritation arises naturally when her pain is compounded by the [[StopHelpingMe attitude]] of [[OldSchoolChivalry her handler]] and [[PityTheKidnapper their target]].
* In ''Anime/NeonGenesisEvangelion'', Asuka is not amused of having periods every months, and adding to the fact, that Shinji has surpassed her, she's even in a worse mood than she is usual.

[[folder: Comic Books ]]

* In the ''SisterhoodOfSteel'' graphic novel, ''Boronwe: Daughter of Death,'' Boronwe's friend and roomate Dindra is bitching about her period while they're playing a board game. Boronwe sardonically asks why it is that Dindra seems to suffer the worst cramps whenever she's losing the game but is perfectly fine when she's winning.

[[/folder]]

[[folder: Fan Fic ]]

* In the ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' FanFic ''FanFic/AVoiceAmongTheStrangers'', the main human character gets hit with this really hard with her first period in Equestria. The fact that there is a language barrier between her and the ponies, and like real horses don't bleed out the crotch when it happens (most likely twice per year) leads to some confusion. The fact that she was under emotional turmoil {{justifie|dTrope}}s it, as she mentions to herself that she hadn't had cramps this bad since she was a teenager, and she's ''never'' been that emotional, [[IncrediblyLamePun period]].
* The MassiveMultiplayerCrossover ProWrestling fanfic FanFic/CharacterChampionshipWrestling, [[{{Ben 10}} Gwen Tennyson]] goes into a rage filled PMS state whenever she is pissed off. Sometimes played for laughs, and sometimes comes with blood...[[{{Squick}} lots of it...]]
* In a ''Literature/{{Discworld}}'' fic [[http://www.fanfiction.net/s/5423228/1/Murder-Most-Orrible about the difference between Assassination and normal ordinary boring murder]], licenced Assassin Miss Alice Band testily says that for a week in every month, a female Assassin is the deadliest thing on Disc as in that mood, she's capable of "[[DeadlyEuphemism inhuming]]" any number of men for fun rather than profit. Her post-menopausal colleague Joan Sanderson-Reeves, who has been there and done that, agrees, but argues the inhumation fees are still jolly necessary, so as to buy expensive chocolate from Weinrich and Boettcher (the most expensive ''chocolatier'' in Ankh-Morpork).

[[folder: Film ]]

* ''Film/ImGonnaGitYouSucka''. While working at the diner, Cheryl tells a fellow waitress that "It's my time" (of the month) and she has cramps. When Leonard tries to kidnap her, she asks him to leave her alone but he persists. She then turns into a character out of ''TheExorcist'' (BlankWhiteEyes, giant Afro, growling voice).
-->'''Leonard''': You must got the Devil in you!\\
'''Cheryl''': No! Cramps! [Slams him up against a wall] I asked you nicely, now I'm going to rip your balls off!
* In ''Film/TenThingsIHateAboutYou'', Katerina's father calls her out on this, after she dents his car in a bout of anger: "[[CrowningMomentOfFunny My insurance policy does not cover PMS!]]"
* In ''Film/{{Carnage}}'', Jodie Foster's character can be seen stashing a package of tampons out-of-sight when she's bringing a guest to her apartment's bathroom. Her emotional fragility during the events of the movie can be at least partially attributed to PMS.
* Used as a throwaway gag in ''Film/MysteryMen''. One of the candidates during the TerribleIntervieweesMontage calls herself the "PMS Avenger" and warns the group that she can only work a few days out of the month.

[[folder: Literature ]]

* Averted in ''TheRedTent''. Although the women all menstruate at more-or-less the same time (Jacob's wives start first, with servants starting a few days later) [[http://en.wikipedia.org/wiki/Lunaception around the New Moon]], and they are secluded (partly because of Jewish laws [[MenstrualMenace labeling menstruating women as "unclean"]], and partly so they can conduct certain religious rituals without any objections), they don't seem to experience adverse symptoms aside from perhaps a little tiredness. It's a restful time, and the women literally celebrate this chance of renewal with offerings to [[MesopotamianMythology Inanna]], socializing, cakes (more like cookies or scones), and fine wine.
* A nice scene in the ''Literature/ProtectorOfTheSmall'' quartet averts this as Kel and her friend/maid discuss what happens during your period. While it does mention that some women do get overly angry, others might just get a little weepy or desire sweets. In the next book, a brief mention is made of Kel having her period and crying over a very bad day when she otherwise wouldn't.

[[/folder]]

[[folder: Live Action TV ]]

* At least one episode of ''Series/MyWifeAndKids'' centres around this, with Michael's wife and teenage daughter both having extreme PMS at the same time.
* Referenced on ''Series/BuffyTheVampireSlayer'', when Willow is consoling her boyfriend Oz, who we've just learned is a werewolf.
-->For a few days a month, I'm not so fun to be around, either.
* A [[http://www.youtube.com/watch?v=hLm5FIKIxMI sketch]] on ''Series/{{SCTV}}'' was about "PMS Awareness Week."
* There have been multiple jokes in ''Series/TheBigBangTheory'' where Penny snaps at Sheldon and he comments that she must be on her period.
* ''Series/{{Roseanne}}'' episode "PMS, I Love You". When Roseanne gets PMS she pretty much goes crazy, with wild mood swings. This causes terror in the members of her family. Oddly though, her issues with this time of the month are never brought up again after this episode.
** In the same episode, Roseanne's friend Crystal, who is most often the [[GlurgeAddict kindest, sweetest,]] most naive and most Woobie-ish of the cast (if a little neurotic,) mentioned how even she becomes a complete she-beast during her time of the month, saying once she went around and broke a streetlight for every man who did her wrong; Dan called it the "Great Blackout of '84."
** In an episode where Roseanne revealed she missed her period and is afraid she might be pregnant again, Jackie asked how she managed it when she's always so horribly mean and angry during her time of the month that everyone would've noticed. She gleefully reveals she ''faked'' her PMS that month, and even tacked on an extra day for the hell of it.
* Referenced in an episode of ''Series/{{Maude}}'' when she runs for State Senate. One of her staffers (who isn't a staffer for very long) says that women are unfit for public office because of their mood swings.
* Sorta referenced in one episode of ''Series/{{Sliders}}'' where the land on an Earth (or at least a US) with a Matriarchal Society. One local guy they talk to says that a Patriarcal Society wouldn't work, in part because women only get mood swings once a month and men have them all the time.
* In ''Series/CommanderInChief'', Geena Davis scornfully suggests that the reason men worry about a female president is: "once a month, will she or won't she push the button?"
* Played for laughs on ''Series/SaturdayNightLive'' in a fake commercial for a pill called "Annuale," which lets a woman have her period once a year, apparently turns women into menstrual menaces ([[AxCrazy one attacks her co-workers with an ax]], a second [[BigEater scarfs down an entire birthday cake at a children's party]], a third [[GroinAttack kicks her husband in the crotch]], punches him in the face, and runs screaming out the room, and a fourth [[AnythingThatMoves French-kisses a dog]]). There's even a SideEffectsInclude warning near the end that states that these once-a-year periods should be told to authorities in advance so officials can lock any woman who takes Annuale up like the Wolfman.
* ''Series/EverybodyLovesRaymond'' features Debra going near-psychotic when she's on her period, yelling and arguing at Ray for even less reason than normal. Ray eventually tapes her rants and plays them back to her as a form of revenge and proof that she's being unreasonable... at which point she goes full-on "weepy [=PMS=]ing woman" and poor Ray's forced to backtrack. It was basically head writer Phil Rosenthal's apology/explanation to his wife.
* "The Camping Trip" episode of ''Series/MarriedWithChildren'' (originally titled "A Period Piece," but the censors objected, despite the fact that ''Married With Children'' never showed episode titles onscreen) dealt with Marcy, Peg, and Kelly having their cycles sync up while in a cabin with Steven, Al, and Bud. HilarityEnsues, and probably contributed to the CrowningMomentOfFunny line in ''{{Anchorman}}'', as their periods attract all sorts of wildlife... including {{bears|AreBadNews}}.
* An episode of ''Series/ThirtyRock'' has Liz wondering why people think her show is demeaning to women. We then see a series of the show's sketches about illustrious women losing it because they are having their periods. Later exaggerated with Avery--she goes from understanding and sensible to wild the second her period started.
-->"YOU STUPID DOUCHE!!!"
* On an episode of ''Series/ModernFamily'', all three of the Dunphy women get their periods at the same time, terrifying Phil. Luke, terrorized, yells that they're all "monsterating." They then turn their wrath on Phil for giving Luke that mindset.
* In the sketch comedy show, ''Touch Me, I'm Karen Taylor'', Karen invented the super-heroine Pre-Menstrual Girl, who is the alter ego of normally pleasant and cheerful office worker Penelope. When trouble arises her super-power kicks in: she alters her body-clock and transforms into Pre-Menstrual Girl, a superheroine who saves peoples' lives, either by winning the villain's heart with her neurotic sobbing, or terrifying him into bludgeoned submission by screaming, being aggressive, and sniping.
* In an episode of ''Series/TheITCrowd'', Jen has a "[[UnusualEuphemism visit from Aunt Irma]]" that makes her so irritable that she screams with the VoiceOfTheLegion. To make matters worse, Roy and Moss start having the same symptoms as though their cycles are synchronizing, even though they're men.

* "Ridin' da Cotton Pony" by Music/DaYoopers hints at this.
* "[[http://www.youtube.com/watch?v=B0lKdYQkMW4 PMS]]" by BobRivers (based on "TNT" by {{ACDC}}).

* Sara from ''ComicStrip/{{Zits}}'' has two turtles; Peaches and Mordoc, Lord of Unholy Fury. Named during different times of the month.

[[folder: Real Life ]]

* Most viral posts on {{Website/Tumblr}} that are about periods tend to focus entirely on the most extreme cases of menstruation and PMS. They almost never even ''mention'' individuals who don't suffer much (if at all) from the side effects, much less the people who get periods but don't have the PMS that's presumed to go hand in hand with it. Outside of that, however, it's '''very''' important to note that the posts themselves [[TruthInTelevision are rarely hyperbolic]] in regards to what the extreme cases are like for those who ''do'' experience them, unless it's being exaggerated for comedic purposes. Indeed, almost all of the viral posts are written by members who ''do'' suffer from the more extreme symptoms of PMS and periods, and if they just so happen [[{{Transsexual}} to be female only in terms of biology]], the frustration with their circumstances [[FromBadToWorse only gets worse]]. Many of the posts are also written and/or drawn in response to people [[ItsProbablyNothing telling them that periods aren't a big deal and that they should "stop overreacting"]], so the members are very likely to believe that mentioning the exceptions would only serve to weaken their argument.

[[folder: Video Games ]]

* This is the only way to tell that ''VideoGame/{{Terraria}}'' averts NoPeriodsPeriod. Most of the female [=NPCs=] become rather irritable during a Blood Moon.

[[/folder]]

[[folder: Webcomics ]]

* How Kyo'nne of ''{{Drowtales}}'', who is a drow, a species that doesn't get periods, [[http://www.drowtales.com/mainarchive/20100215c21p021.jpg explains what a period]] is to another drow, when her human companion is on their period.
* ''Webcomic/CodeNameHunter'': Ruby suffers from some of this just before the Treaty Night event.
* ''Webcomic/{{Sinfest}}'' occasionally highlights the PMS cramps/cravings of Monique, its single human female character.
* [[http://xkcd.com/594/ This]] ''Webcomic/{{xkcd}}'', though the woman suffering PMS is grumpy less because of her condition and more because her boyfriend [[LamePunReaction takes the time to crack a bad pun]].
* Parodied in this [[https://www.youtube.com/watch?v=BD8gijwTZ2Y animated webcomic]]. One girl is visited by a personification of periods and is swiftly punched in the crotch. Her friend sitting nearby just gets some affectionate slaps, and thus is in no pain at all when her period occurs.

[[folder: Web Original ]]

* ''[[http://www.youtube.com/watch?v=8J1LfcvqhcQ Fem Fortress]]'', a fan-video of ''VideoGame/TeamFortress2'' that swaps out the male voices for female ones (but not the models, oddly enough). Everyone on the team goes on their period ''at the same time'', and are unable to fight. [[spoiler:Except the Pyro.]]

[[folder: Western Animation ]]

* Played with in the ''[[WesternAnimation/{{Sixteen}} 6teen]]'' episode "Enter the Dragon" where the girls' cycles sync up. Caitlin does have PMS, but Jen has cramps and Nikki becomes overly needy.
