Maggie Sheffield: So?
Fran: So, women don't get their period every week. If they did, all the men in the world would be institutionalized.
Having to deal with bleeding and cramps every month can suck. But for all the other days, it can be a handy excuse if one has to sneak out of work, keep folks from searching your stuff, or abandon politeness for whatever reason (since everyone knows all periods cause bad moods).
Bringing up one's own period in fiction usually results in men not wanting to hear any more quickly, due to the assumption that All Periods Are PMS.
- In an ad for a period-products delivery service called "Hello Flo," a young girl is hoping her first period would come, because she's the only one in her social circle who hasn't gotten it yet. She then gets the idea to fake it: she puts some red nail polish on a pad, and leaves it where her mother is sure to find it. Her mother does, and proceeds to throw her a "First Moon Party," to which everyone (even Grandpa!) is invited. The girl is so embarrassed, she confesses that she faked it, and the mother replies that she knows. The girl then asks if her mother is going to ground her for lying, and the mother replies, "Why do you think I threw you that First Moon party?" (Implying that she felt the embarrassment was punishment enough.)
- At one point in Horimiya, Ishikawa claims that Miyamura is having his period to explain why he can't go to the baths with everyone else (the real reason is because they'd find out about his tattoos). The other guys don't even question this despite it being a Blatant Lie. Miyamura would later reuse this excuse to get out of having to take part in a mandatory pool class.
- Indirect example in The Second Try. Misato claims that Asuka is having her period to explain why her Sync Ratio had dropped.
- With Pearl and Ruby Glowing: Yue sometimes slit her thighs to make it look like she was "unavailable" because of how rough Hahn was in bed with her.
- In The Amazing Spider-Man, Peter Parker crashes into Gwen's room while heavily wounded. To keep her father Officer Stacy from finding him, she calls off all requests to come down for dinner, then starts to apologize for her outburst by blaming it on period cramps. Immediately her dad doesn't want to hear any more.
- In Fantastic Beasts and Where to Find Them, Queenie smuggles Newt, Tina, and Jacob out of the MACUSA headquarters by claiming she's feeling unwell and taking the rest of the day off. When her supervisor asks what she's carrying in Newt's suitcase, her response is "lady things."note She even invites him to take a closer look, but he declines and sends her on her way.
- In Monty Python's The Meaning of Life, a diner, faced with the appalling prospect of having Mr. Creosote at the next table, uses the excuse of suddenly realizing she's having a really heavy period and consequently not wishing to bleed all over the carpet, as her excuse to get the hell out of the place quickly. Her husband doesn't seem to be onboard with this excuse, as he only claims they have a train to catch.
- A variant in Are You There God? It's Me, Margaret.. Nancy pretends to get her first period to try to impress her friends. This backfires when it actually does happen later and Margaret witnesses Nancy panic.
- In an Ellery Queen novel, a woman leaves work early by claiming a "a particularly feminine problem, connected to the phases of the moon".
- The Bible: Older Than Feudalism. In the Biblical Book of Genesis, Rachel steals her father's idols just before she and her husband's caravan leave. When her father catches up to Jacob and accuses him of stealing, Jacob lets him search his entire property, saying (not knowing who did it) that anyone who stole the idols will be put to death. Rachel keeps her father from finding them by sitting on top of the saddle where she hid them, while claiming she's on her period and thereby making anything she touches unclean. As a result, he never finds them.
- Adolin complains about women doing this in Oathbringer. Apparently one of his ex-girlfriends once managed to supposedly be on her period four different times in the same month.

- Agent Carter: In the first episode, Peggy overhears her fellow agents planning a secret infiltration of a nightclub hiding stolen weapons. Not invited along due to being a woman, she asks to go home early due to "female matters", and promptly gets the time off to plan her own investigation.
- When Catherine of The Great is told to be nice to her terrible husband, she goes and apologizes, explaining that she had a very long period.
Peter: She explained her blood was in for weeks, apparently, which is strange but...may be an Austrian thing. So let us forgive her.
- Hunter. Rick Hunter has been ordered to work with a partner to inhibit his Cowboy Cop tendencies, and works out a deal with Dee Dee to pretend they're partners while they're actually working alone. When Da Chief demands to know where his partner is, Hunter comes up with this excuse, saying the department wouldn't want to get involved in a sexual discrimination lawsuit over it. Da Chief is not impressed.
- Ramy: In the second episode, Ramy's sister Dena tells their sexist uncle Naseem that she's on her period. Uncle Naseem immediately excuses her "attitude" and tells her to go for a walk, an opportunity she immediately seizes to get out of the family dinner.

- Yellowjackets: The team's flight crashes and the survivors have spent weeks in the Canadian wilderness. They have been out there for so long that the girls' cycles have synchronized. The only one NOT having her period is Shauna. She even uses deer blood to fake it to hide the possibility of being pregnant.
- Emilie Autumn's "Marry Me": "Then I take a glass and I slit my own innermost thigh / So I can pretend that I'm menstru- well, unavailable."
- Be More Chill: Right before "Michael in the Bathroom", Michael is sitting alone in the bathroom after Jeremy betrays him and someone knocks on the door, demanding to use the bathroom. Michael yells back that he is on his period so he doesn't have to leave. Somehow, the other person believes him.
