"I'd much rather see a pregnant woman standing up on a bus, than a fat girl sitting down, crying"
—Jimmy Carr

A character (usually male) overhears a conversation or finds some evidence that leads him to mistakenly believe another character is pregnant.

If the suspected pregnancy is with his love interest, he will freak out over the thought of being a father. The episode will be about his attempts to cope. He will have accepted the idea by the end, and will be mildly disappointed when he finds out that it was a false alarm.

If the suspected expecting woman does not have an established love interest, he will try to determine who the father is. Usually he will pinpoint some character that she has romantic tension with, but is not sleeping with. He will confront the suspected father, but will dance around the word "pregnant", leaving the suspect completely bewildered as to what's going on.

In any case, he will walk on eggshells around the not-so-expectant Mom, and will tell everyone except his suspects what he thinks is going on. This may lead to some Alcohol Is Poison moments as the poor woman wonders why everyone looks horrified that she's sipping at a glass of wine.

During the course of the episode, everyone will be convinced she is pregnant except for her.

In order for this trope to work, several characters have to be using the Idiot Ball that week. Yet, it may be Truth in Television.

An alternative is when a woman is assumed to be pregnant due to having what appears to be a sufficiently large, protruding stomach (which can lead to extreme awkwardness for obvious reasons), or displays quirks that could be mistaken for stereotypical "pregnancy traits", such as random bouts of vomiting, extreme appetites and Wacky Cravings. Pillow Pregnancy is when a woman invokes this trope, usually on purpose, by concealing something under her clothes.

Contrast its inversion, Surprise Pregnancy.

Examples of Mistaken for Pregnant include:

Anime & Manga

  • In an example of Cleaning Up Romantic Loose Ends, the end of Maison Ikkoku has Mitaka discover that "she" is pregnant. After a previous drunken night with his arranged girlfriend Asuna he assumes that he got her pregnant, and vows to marry her to set things right. After he proposes and everything is set in stone, she decides on a dog's name for the new... puppy. Her dog had actually been the one knocked up by his dog. Still, Mitaka and Asuna do end up Happily Married.
  • Keitaro had to deal with this in Love Hina, when he and everyone else woke up to find Mutsumi sleeping naked in his futon with him. Mutsumi's comments about last night being great and the test being "positive" had even Keitaro himself thinking he knocked her up. Actually, she just fell through the hole in Naru's room, decided to sleep where she landed, and was referring to Keitaro's help in studying. When Keitaro expresses mild regret about the misunderstanding, of course, he's chased off by Naru (vowing to personally neuter him).
  • In Detective Conan, this is how the author slyly confirms something that fans had been speculating about: that Miwako and her boyfriend Wataru are sleeping together. More exactly: Miwako loses a ring that Wataru had given her, off-handedly mentions that "something" is missing, Wataru and others mistakenly think that she's missing her period, Wataru immediately believes that he's the prospect babydaddy (something that would make zero sense if they weren't sexually involved), etc.


  • In one issue of the Gold Digger comic, Charlotte the Harpy is mistaken for being pregnant when she staggers off of a plane, groaning in pain and looking distressed with her stomach bulging. A doctor immediately starts prepping her for delivery, after some mild shock at discovering her race, only to discover that she's not pregnant at all: Charlotte had (seriously) overindulged on complementary peanuts and pretzels while aboard the plane. What he mistook for labor pains was the resultant stomach-ache from hell after stuffing herself into a Balloon Belly. Charlotte herself is somewhat disappointed when she's told this means she is not going to have a baby.
  • In one Calvin and Hobbes storyline, Calvin's mom is sick, and Hobbes wonders if she's pregnant. Calvin later asks his parents, and his dad mentions that if she was, she'd look like "a hippopotamus with gland problems".

 Calvin: And that's when mom whacked him with her pillow

Hobbes: You have weird parents

  • An issue of Mad Magazine had a feature on conversation "saves"; that is, how to rebound from a potentially embarrassing mistake. One example featured two women at a bus stop; the first asks the second, "When are you expecting...?" The second woman, who is heavyset, replies, "I'm not pregnant." The first woman finishes her sentence: "...That darn bus to arrive? It's always late!"


  • Can't remember what the commercial was for, but 2 women are in the supermarket when one thinks the other is pregnant and congratulates her and says that it's probably a girl because she's carrying low. The other woman (who looks like a cross between Sassy Black Woman and Brawn Hilda) angrily replies, "I'm not pregnant! Just WHAT are you trying to say?!"


  • A Gakuen Hetalia fic involves the Bad Touch Trio discovering that Chun Yan is binding her breasts, looking stressed, and hanging around the counsellor's office a lot, and assume she's trying to conceal a pregnancy. Chun Yan, a.k.a. Yao, is actually trying to transition to living as male.
  • Drives the entire plot of the Cori Falls fic "Family Matters." Though it's less "James suspects Jessie's pregnant" and "Jessie mistakes herself for pregnant due to her symptoms" and James is instantly ecstatic about being a father, the ending is still spot-on with the false alarm and his disappointment.


  • In While You Were Sleeping, Lucy is at one point mistaken for pregnant by the family who believe she's engaged to his comatose son (she isn't). This leads Jack, the man's brother, to announce this misconception to all of her friends at a New Year's Eve party when he tries to prevent her drinking an alcoholic beverage. Not surprisingly, Jack ends up with a lot of apologizing to do.
  • In Bridget Jones: The Edge of Reason, Bridget tries to buy a pregnancy test, but she is unable to speak the local language and everyone in the store ends up thinking she already is pregnant.
  • In Two Weeks Notice, George Wade commits this while interviewing a job candidate.
    • And later in the movie they meet each other again. She remarks that now she's pregnant and he can congratulate her. George thinks that she's playing a trick on him, so he refuses to believe it. Thus she gets mad at him again.
  • "Is she pregnant?"
  • In Grown Ups, a pregnant character claims to be this when asked about her pregnancy. Cue momentary mortification from the asker. Of course, this only lasts thirty seconds to a minute, maximum.
  • Inverted on Clueless, where the somewhat geeky girl tutoring the protagonists keeps leaving to throw up. They assume she has an eating disorder; it turns out she's pregnant.
  • "Large" Marge in Horrible Bosses.


  • In one of the Heralds of Valdemar novels, a court fashion of elaborate and extremely heavy veils (Which required the ladies wearing them to walk while leaning backwards to support the weight on their heads) met an abrupt end when a man new to the court asked the two ladies who started the fad when their babies were due.
  • This is the subplot of The Baby Sitters Club #24. Kristy's mother is more emotional than usual, talks about having another child in the family, and everyone keeps asking if she's pregnant. She's not. She and Watson just adopted little Emily Michelle from Vietnam and were keeping it a secret.

Live Action TV

  • Hal from Malcolm in the Middle does this to a prospective employer, rubbing her belly and playfully asking "Oh, and what have we here?" to which the woman replies in a mock-cheerful tone that it's her big, fat stomach.
  • Three's Company did Mistaken for Pregnant at least four times ("Will The Real Jack Tripper...," "Stanley's Hotline," "And Baby Makes Four," "Jack Be Quick,") plus one episode ("And Baby Makes Two") where Janet was mistaken for trying to get pregnant.
  • Friends: "The One With Chandler and Monica's Wedding" and "The One After 'I Do'". In this one, Phoebe found a positive pregnancy test and Rachel (whose test it was) allowed everyone to assume it was Monica's. Then when Phoebe learnt the truth, but Rachel still didn't want to tell anyone, she claimed she was the one who was pregnant. This leads to Joey proposing marriage so she won't have to go it alone.
    • Played for comedy in another episode where Monica kept getting mistaken for preggers. She blames the baggy shirt she's wearing.
  • Let's try to list all the times someone was Mistaken for Pregnant on 7th Heaven: Annie by Eric, when she was really starting menopause; Sarah and Matt by their parents, when her period was just late; Ruthie by many in her school; two of Simon's girlfriends/fiancées by, one-by-one, everyone...
  • Joan of Arcadia included an episode where Helen has a positive return on a pregnancy test. However, Luke finds the test, believes it's Joan's, and spends most of the episode panicking about being an uncle. As with Friends, unusual in that someone actually was pregnant (although the episode ends with Helen revealing she had her period that evening, indicating an early miscarriage).
    • Or a false positive. They're fairly common.
  • In Frasier, Niles half-hears a conversation between Daphne and Frasier about the need to keep Roz's pregnancy a secret, and concludes that Daphne is pregnant and Frasier is the father. Things escalate from there until he challenges his brother to a duel for Daphne's honor.
  • An episode of I Love Lucy had Lucy and Ethel convinced that Ricky and Fred were about to join the army. They decide to show their support by knitting socks; Ricky and Fred notice them knitting and assume that both their wives are pregnant.
  • Dads Army featured a now Missing Episode in which the entire cast mistakenly believes Mrs Pike is pregnant, when in fact she has arranged to take in an evacuee child. After its original broadcast in the 1970s, it received viewer complaints that the plot was too crude.

  • Dinnerladies: Bren was mistakenly thought to be pregnant at one point because she refuses to donate blood during a blood drive, and later during the same episode mentions feeling dizzy and unwell. Turns out she just has a phobia of needles, and as she puts it, is very unlikely to be pregnant "unless sperm can get through sash windows".
  • 3rd Rock from the Sun has Sally hanging out with pregnant women, much to the shock of Don, her love interest. According to Dick (who thinks the conversation is about shoes), "Pickles did it. Harry watched it happen."
  • In the first season of Gossip Girl, this is the catalyst for Blair's social downfall. Serena covers for her to buy her a pregnancy test, so she is initially Mistaken for Pregnant as well.
  • Liz Lemon in the second season finale of Thirty Rock mistakenly thinks she's pregnant, caused by eating one too many bags of Sabor de Soledad. It's played with in a scene when she goes through calendars, stating that she should cross off the days when she last had her period "like people do in movies." Jenna also discovers the positive pregnancy tests, and is distressed because "someone's going to get more attention than me!", and Dennis, the presumed father, hangs out in Liz's apartment (uninvited), listens to her voicemail, and immediately lays out his plans for the baby, such as naming it Morpheus.
  • In a later episode of Boy Meets World, Topanga's decision to go on a diet is mistaken for pregnancy when Topanga refuses breakfast, can't fit into Cory's pants, and Cory later overhears her talking to Eric about "getting through this".

  • Jimmy Carr also made a joke about this. When asked why he refuses to give up his seat for a pregnant woman on public transport, his response was: It's better to see a pregnant woman standing up than a fat woman sitting down, crying.
  • The various tabloid articles on baby rumors, showing photos of actresses who simply look like they exhaled.
  • Women who are actually pregnant will sometimes invoke this trope when strangers start asking questions that are, quite frankly, none of their business ("How far along are you?"

  • Certain medical conditions also cause weight gain to be located in certain areas. Type II Diabetes causes people who have it to be trunk heavy. Polycystic Ovarian Syndrome (PCOS), which is also characterized with insulin resistance, causes unusual weight gain, particularly in the belly. It is also a leading cause of infertility, making any assumption that the woman is pregnant MUCH more painful than an implication on her weight.
  • The so-called Flora Hastings Affair at the beginning of Queen Victoria's reign. The Queen accused one of her ladies-in-waiting to be pregnant and thus having lived a scandalous lifestyle. Flora Hastings' growing belly seemed to support the thesis until it turned out that she had had a tumour and died shortly afterward. The Queen's approval rating sank heavily after this and she had much apologizing to do.
