My Secret Pregnancy

Pregnancy and gestation can usually be hidden at least a couple of months after a woman discovers she is pregnant. For this reason, a pregnant woman always holds a slight edge in the information department over the father of the child in that she can generally control the time and place of The Reveal.

Sometimes, though, she'll decide to simply not reveal at all. At least not right away. And often never, at least on purpose. The character in question has decided to have a secret pregnancy.

This might, of course, sound cruel and unnecessarily mean, but there are several reasons for why she would want to do such a thing. If the father is an insane, planet-killing psycho worried that his spawn will one day try to kill him and steal his power, well, secret might be a good idea. If he's an irresponsible lout, she might decide the kid would be better off without him, since he would just be a Glorified Sperm Donor. She might just want to be a single mom for some reason. Or she can't think of any good way to tell him and is just "waiting for the right time". Even if it's several years from now. Perhaps she was drunk, or otherwise does not know in Who's Your Daddy?, or believes that the father will not believe her in Mama's Baby, Papa's Maybe.

Sometimes she'll keep a secret because she loves him too much to tie him down. The father rarely appreciates this selfless gesture when he finds out.

Also note that the father is simply the most common individual from whom the secret is kept. A sufficiently advanced Ancient Conspiracy may also or instead be the target of the secret. In some cases, the woman herself may be completely in the dark because she hasn't experienced the regular symptoms. A woman with irregular periods, for example, might not notice a significant change.

Note that in Real Life there are cases in which a woman literally doesn't know she's pregnant until well into the second or third trimester, and sometimes not until birth. Whether it's due to mental problems, drugs, extremes of weight, carrying the baby unusually (more common than young people realize), or whatever, it's somewhat rare but not extremely so. In 2008, for instance, an average-sized, otherwise perfectly healthy woman in England carried twins to 28 weeks without showing or missing a period; she found out she was pregnant less than two weeks before the babies were born prematurely at two pounds each. (They both survived.)

Not to be confused with Hide Your Pregnancy, which is the meta version of this.

Anime and Manga

 * In the manga My Girl by Sahara Mizu, the hero's high school girlfriend ends up going abroad to study just to hide her pregnancy (and later, the child herself) from him—she doesn't want to burden him with it. (Of course, then she dies, and he's stuck with the kid anyway...)
 * The manga March On Earth. The hero's older sister chooses not to tell the father of her child so that he won't cancel his career-vital overseas stay, and keeps who the father is secret from everyone else so that they won't contact him. She doesn't anticipate dying and having the younger sister get a Promotion to Parent since there's literally no other living relative.
 * In One Piece, Portgas D. Ace's mother Rouge hid her pregnancy for 20 months to keep the World Government from finding her son, whose father was none other than . Seeing as humans in One Piece are Made of Iron she pulled this off, though she died soon after he was born from the strain.

Comic Books

 * In Usagi Yojimbo, Usagi returns to his home village for a time, where his former love has been married to another man for several years. The woman has a kid, and Usagi grows quite fond of the little tyke, especially since the guy starts calling him "Uncle". Before long, however, the revelations start: It's really Usagi's kid, of course, and his love didn't want to tie him down (since he's a samurai who needs to be able to travel). After a discussion, Usagi decides not to stick around, lest he drive a wedge between the boy and his adoptive father. Then, somewhat later, it's revealed that . But neither, believing that the other doesn't know.
 * Aside from that, there's also Kahvi from Elf Quest, who can't hide her pregnancy, but does tell the father that it's not his kid, and that the kid died shortly after birth anyway. Then she raises the kid as the ultimate counter-weapon to the father's incredible magic power (and ego).
 * The infamous Sins Past storyline that retconned in Gwen Stacy becoming pregnant with and giving birth to twins (albeit in appreciably less than nine months) without Peter or anyone else noticing into the continuity of early 1970s The Amazing Spider-Man.
 * Rose Canton (the Golden Age Thorn) pulled this one on Alan Scott (the Golden Age Green Lantern. First she married him under a false identity, then she disappeared during the honeymoon, after an explosion that led him to think she had been killed. She had twins, which she gave up for adoption out of fear that her evil Thorn self would harm them, and they grew up to be the superheroes Jade and Obsidian. (Note: this is the short version!)
 * In the Bronze Age incarnation of Superman, the Kents claimed that Clark was born from one of these. Since Martha Kent had miscarried multiple earlier children, the neighbors were willing to accept her not wanting to mention being pregnant again, and since Clark was 'born' in the middle of winter after a massive blizzard snowed the Kents in for well over a month, nobody other than her husband would have seen her during the time frame when she would have have been visibly pregnant, so everyone accepted their explanation.

Fan Fiction

 * In one Metal Gear Solid Fanfic, it was mentioned that

For several months he actually thought she was just fat. She also decides to keep this from her demanding boss for a time so it might not interfer with work. Humorously, the boss actually knows when she tells him ("You thought I thought you went out and got fat? I don't care if you work while giving birth."
 * In Dreamgirls,
 * In Saved, good little Catholic girl Mary has sex with her gay boyfriend in an attempt to "cure" him. She successfully hides the resulting pregnancy for months because pregnancy at her school is "about as common as the bubonic plague."

Literature

 * In Marion Zimmer Bradley's Centaurus Changeling, Beth hides her pregnancy from her husband. The only problem is that, as she soon discovers, the air on the planet they are living on is highly poisonous to pregnant women...
 * In romance novels, the most common reasons are either that she doesn't want to make the man feeled tied down (because she's been sleeping with him but doesn't want him feel like she trapped him into a marriage; almost inevitably followed by him finding out an reassuring her that he really does love her and of course they should get married) or because society will ostracize her if they find out (more common in historical novels, of course).
 * In Tom Clancy's novel The Bear and the Dragon, a woman living in the People's Republic of China conceals that she's pregnant, as the unborn child falls afoul of the PRC's "One Child" policy, and thus would be subject to being aborted. (While one can get a permit for another child, when the first has died, as was the case in this example, the woman in question was part of a known Christian family, so the obstructive bureaucrats of the region denied the couple's permit request.)
 * The Thornbirds
 * Meggie goes so far as to sleep with her estranged husband one last time to create an alibi. Justified, as the actual biological father is  He only finds out years later, after Hilarity most definitely does not ensue.

 * In the other book about a young woman being a single mother in the '60s before it's fashionable (Margaret Drabble's The Millstone), the narrator also doesn't tell the father that their one night stand had results, and when she happens to see him again, lies about the age of the baby so he won't put two and two together. This is a 'not wanting to burden the father one'.
 * Angie Branzino, in June Casey and Joan Triglia's Bound By Blood. She actually goes so far as to wear a corset until the sixth month (and only ditches it then because she gets found out).

 * In the Doctor Who episodes "The Empty Child"/"The Doctor Dances", the mother keeps her pregnancy secret from everyone. Of course, we only find this out years after the fact.
 * A New Series 4 episode has a woman return from abroad and spend the next few months in her room, claiming severe illness. Of course, she's really pregnant. Also, this was the late 19th century, she was unmarried, and the father was, so she had some pretty good reasons to hide.
 * does a very good job of this. Of course, she's  because
 * Peggy on Mad Men, being a nice Catholic girl who had had sex just that one time when she got pregnant, didn't even find out for herself until going into labor; even after the baby's been put up for adoption, she doesn't mention it to anyone, even the father, .

 * The Discovery Health Channel show I Didn't Know I Was Pregnant subverts this as in every episode the woman does not know that she is pregnant until just before she gives birth.
 * Scully hides her pregnancy from everyone except A.D. Skinner for several months on The X-Files. The reason for hiding it is never really given, though there are It wasn't until close to the birth and after William is born that we find out  .

 * A tragic version on Earth: Final Conflict. Sibohan Beckett and Ron Sandoval were raped by Ha'Gel. Sibohan is captured by the Resistance and gives birth to Liam in captivity. The Resistance decide to mindwipe her to prevent her from revealing their hideout to the Taelons, with the caveat that if she remembered Liam was her son, it would cause the alien implant in her head to overload and kill her. She eventually does, and the only comsolation is that Liam's by her side (and Sandoval's watching from the shadows) as she dies.
 * Due to some genetic Applied Phlebotinum, Peacekeepers can keep a pregnancy in status for up to 7 cycles (years.) As a result, it isn't difficult for Aeryn to hide her pregnancy from John...until Noranti spills the beans, anyway.
 * In Quick Change, the female bank robber keeps her pregnancy secret from her boyfriend, the ringleader, firstly because she doesn't want anything to distract him from the heist they're pulling off and wants to wait until they're away and free to spring the good news, then because she doesn't like what he seems to be turning into following the heist. Unfortunately, she confides in the less-than-bright third robber, who accidentally spills the beans.

 * K'Ehleyr from Star Trek: The Next Generation doesn't tell her son Alexander's father about him until he is three years old, and probably would've waited longer if she hadn't been sent back to the Enterprise. Worf is understandably pissed.

Western Animation

 * Homer was in the dark during most of the time Marge was pregnant with Maggie, in part because she knew Homer planned to just stay with two kids and keep his dream job at the bowling alley and didn't want to upset him. Her sisters, wanting to see Homer suffer, spread the news around town. However, Homer was far too thick to see the signs, understand the congratulatory euphemisms, or notice the outright statements of his soon-to-be fatherhood, and in fact only fully understood after someone congratulated him on his new job due to Rule of Funny.

Real Life

 * During the reign of Louis XV of France, a young woman who gave birth to his stillborn child was charged with infanticide because she had hidden the pregnancy. Remember that as this was a classical European monarchy, and France, she was unlikely to have been stigmatized for this. The King's mistress, Madame du Barry, pleaded with the King to spare the girl's life; her request solidified his love for her because it was the first time she had ever asked him for anything, and it was for someone else. Later on she asked him for quite a bit for herself, to put it mildly.
 * Sex columnist Dan Savage notes in his book The Commitment how his parents got married after a brief engagement and in a borrowed wedding dress because they were expecting, and didn't want their Catholic families to know they conceived a child out of wedlock.

 * In the late 1990's a woman made the Seattle news after she went to the hospital with terrible stomach pains and delivered a healthy 6-pound baby girl. As her periods had always been light and irregular, and she continued to spot throughout the pregnancy and had no baby bump at all, she had no idea she was pregnant until she gave birth.
 * Nobody outside Sarah Palin's immediate family knew she was pregnant with Trig, her fifth child, until she was seven months in. For a forty-something, mother-of-four governor that's not unimpressive.
 * Secretly Pregnant, a TLC show, dealt with women that hide their pregnancy for whatever reason. For example, one woman hid her pregnancy because she was 40 years old and pregnant by a 19 year old.
