History TeenPregnancy / AnimeAndManga

* In ''Manga/The100GirlfriendsWhoReallyReallyReallyReallyReallyLoveYou'', Hahari was only 13 when she gave birth to Hakari. Unlike other examples of the tropes, sex wasn't involved - Hahari had herself artificially inseminated.

* ''Anime/MobileSuitGundamIronBloodedOrphans'' has a rare example of teenagers ''[[InvokedTrope trying]]'' to have a baby; Atra, due to some advice from Haba, comes to believe in that if Mikazuki had a child, he'd stop his self-destructive habits since he'd have something to live for. She first tries to get Kudelia to do it, who refuses and suggests Atra should be the one to have the child, since it was her idea. Though Mikazuki, who had recently developed an interest in babies, agrees, she comes to realize that even with a child, Mikazuki will never change. [[spoiler: In the end, however, they still conceive a child just for themselves, a son named Akatsuki, who Atra raises with Kudelia's help [[SomethingToRememberHimBy after Mikazuki's death]] ]].

* Hori's parents in ''Manga/{{Horimiya}}'' were around 18-19 when she was born. [[spoiler:Becomes a case of GenerationXerox in the original webcomic when Hori has to drop out of school in her senior year due to getting pregnant with Miyamura's child. Post-TimeSkip chapters have [[HighSchoolSweethearts the two of them married]] and raising their son together.]]

* In ''Anime/DigimonTamers'', some maths will reveal that Ruki's mother Rumiko had her when she was eighteen. The dub changed Ruki's age without touching Rumiko's, so if we go by AllThereInTheManual, the latter gave birth at ''fifteen'' instead. However, in the actual series, Rumiko did say [[DubNameChange Rika]] was the product of her being married before she was ready, so eighteen is still the youngest she could have been. Her grandmother Seiko is also very youthful-looking and could be an example in the dub if, as theorized above, Rumiko's age actually ''is'' higher in the dub (in the original, Seiko had Rumiko at age 21 and thus became a grandmother at age 39).

* ''LightNovel/GonnaBeTheTwinTail'': Miharu, Souji's mom. However in her case, it's absolutely merited; the light novel mentions that she got pregnant with Souji during her ''third year'' (it's not specified, but the assumption is high school due to the fact that said conception happened in the middle of a ''[[Main/MrImagination chuunibyou]]'' roleplay, though middle school is not out of the question), putting her around 14-18 when she had him.

* In ''LightNovel/{{Toradora}}'', male lead Ryuuji Takasu was born when his mother, Yasuko, was about 16-17.

* In ''Anime/SuperDimensionCenturyOrguss'', all female Emaan who are mothers go through at least one of these, because their BizarreAlienBiology makes them ''sterile at eighteen'', in a bizarrely enforced case of ChristmasCake.

* [[spoiler:Tsubame/Top Speed]] in ''LightNovel/MagicalGirlRaisingProject'' zigzags this. She's 19 when the story enters with her carrying a child (unknown to her fellow magical girls). However, she is HappilyMarried (though still doesn't give a good impression to her neighbors). [[spoiler:Tragically, she does not carry her baby to term as she's killed in battle.]]

* This happens to Ed's friend and ImpliedLoveInterest Rose in ''Anime/FullmetalAlchemist''. She's heavily implied to [[spoiler:have been raped]], [[ChildByRape and her kid was born from that]]. She's seen with her son the second time we see her and by her cameo ''Anime/FullmetalAlchemistTheConquerorOfShamballa'' he's a toddler.
