That's because once a woman is pregnant, changes in her hormones typically prevent her body from continuing to ovulate, Dr. Greves explains. But if a woman does ovulate again—and if that egg becomes fertilized and implants in her uterus, she can carry a double pregnancy.
The reasons why a woman might ovulate while she's already pregnant aren't well studied. The truth is not all medical phenomena have a logical explanation.

She cites one previous case report in which doctors identified a four-week discordance between two fetuses.
In other words, one fetus appeared to be four weeks older than the other, which suggested a superfetation pregnancy. Does that mean you will have more than one baby? If the question has piqued your interest, this article can be quite a read.
Here, we shall talk about the chances of ovulation during pregnancy and some more factors associated with it. A straightforward answer to the possibility of ovulation while being pregnant is a simple no.
In scientific terms, ovulation is the process where the ovaries release an egg during a menstruation cycle. This egg then makes it away through the fallopian tube and, if sperm is present there, it will end up being fertilised.
A fertilised egg then finds its way to the uterus where it awaits implantation. This shedding of the lining is what constitutes your period. When you are already pregnant, the body is aware of this and does not undertake any processes to release the egg or proceed with ovulation. The uterus, tubes and ovaries all form part of the same system, so the presence of an embryo automatically triggers these processes to shut down. Despite this science, you might come across various sources that claim ovulation does occur during pregnancy.
Or, you might take an ovulation test and get a positive result post which your pregnancy could be confirmed. Both the positive test results may leave you confused. These tests do not actually check whether the ovaries are releasing an egg or not. And, since the hormones undergo a substantial change when pregnancy sets in, those levels might be a little too high, triggering the test to reveal positive result for ovulation. Therefore, a positive result for ovulation test might purely be a result of hormonal fluctuations or even a fault test for that matter.
