There will be a difference in gestational age with a double pregnancy, because the two babies were conceived at two different times even if a few days or weeks apart.
There may also be a gap in the size of the fetuses, but this is also common in regular twins when one twin takes more nourishment than the other, according to research. Twins can also simply grow at different paces, Dr. Minkin notes. And, Dr. Minkin points out, twins are from two presuming fraternal twins, not identical eggs released at the same time, with the same father. A double pregnancy could technically result from two different sexual encounters with two different people.
Again, that would have to rely on a woman ovulating multiple times within a cycle, or ovulating once already pregnant, and the second pregnancy taking successfully. Because this is so rare, there are no documented symptoms or tell-tale signs of a double pregnancy. Doctors may not even be able to tell the difference between superfetation and a twin pregnancy, unless there is a stark difference in gestational age or size as in the woman with two uteruses who gave birth to babies 26 days apart.
Superfetation may only happen in one out of a few million pregnancies, research suggests. A woman might not have any idea she was dealing with a double pregnancy until the babies are actually born, especially if they are very close in gestational age. Minkin says. Finally, a plug made of mucus forms in the cervix to prevent sperm from swimming up into the uterus, according to Scientific American. But in a few out-there cases — including Allen's — those automatic defenses don't appear to have worked.
In , for example, one British woman gave birth to a boy and a girl conceived three weeks apart , according to TIME. Jennifer Ashton told "Good Morning America" that we still don't know exactly why superfetation happens. So far, case reports indicate that the second pregnancy tends to happen roughly two to four weeks after the first one. And since the babies are so close in age, a mom who experiences superfetation faces similar risks to a mom expecting multiples: A higher risk of preterm birth, high blood pressure , and preeclampsia.
Most importantly, she stressed that superfetation is really rare. As she said on the show: "I want people to know that you have a better chance of being struck by lightning or winning the lottery than having this happen to you, if you're a woman with a uterus.
