Mistaken for Pregnant

""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.

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 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.
 * 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 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".


 * An issue of Mad Magazine had a feature on conversation "saves"; that is, how to rebound from a potentially embarrassing mistake.

The first woman finishes her sentence: "...That darn bus to arrive? It's always late!"

Commercials

 * 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.

Real Life
"Counsel: Is there anything about your physical condition that might make it difficult for you to serve in this case?

 * 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.

The Queen's approval rating sank heavily after this and she had much apologizing to do.
