It's such a rare occurrence that medical experts have only been able to identify a few confirmed cases of superfetation in pregnant women. So, while yes, you could get pregnant while you're already pregnant, it's probably not something to worry about.
A double pregnancy, or superfetation, is extremely rare — in fact, there aren't even stats on how often it happens — but it's scientifically possible. We're not saying you should worry about it happening to you, just that you can't say that it's impossible. Here's why.
There have been a few case reports of superfetation in women. Most had been undergoing assisted reproduction techniques, like in vitro fertilization. Superfetation results in two fetuses with different ages and sizes. Despite this, it's possible for both babies to be born fully developed and completely healthy.
It's possible to get pregnant before your first postpartum period, which can occur as early as four weeks after giving birth or as late as 24 weeks after baby arrives (or later), depending on whether you're breastfeeding exclusively or not.
You may get varicose veins — blue or red swollen veins most often in the legs — or hemorrhoids — varicose veins of the rectum. Hemorrhoids can be painful and itchy and can cause bleeding. You may also get stretch marks where your skin has expanded. Braxton-Hicks contractions, heartburn, and constipation may continue.
Usually, the pregnancy losses at 8 months and 4 months will be due to obstetrical complications such as placental abruption, infection, high blood pressure, or any of a number of medical problems.
You can get pregnant as little as 3 weeks after the birth of a baby, even if you're breastfeeding and your periods haven't started again. Unless you want to get pregnant again, it's important to use some kind of contraception every time you have sex after giving birth, including the first time.
You're most fertile at the time of ovulation (when an egg is released from your ovaries), which usually occurs 12 to 14 days before your next period starts. This is the time of the month when you're most likely to get pregnant. It's unlikely that you'll get pregnant just after your period, although it can happen.
While this is different for everyone, women can start ovulating again as soon as three weeks after having a baby. It's even possible to get pregnant before you get your first menstrual cycle during the postpartum period.
Superfecundation is the fertilization of two or more ova from the same cycle by sperm from separate acts of sexual intercourse, which can lead to twin babies from two separate biological fathers. The term superfecundation is derived from fecund, meaning the ability to produce offspring.
Although this is quite rare it can happen and it's called superfetation. Two babies are conceived from separate acts in two different cycles. These babies can be from the same father or two different men. When heteropaternal superfecundation occurs, the babies are from different fathers.
In rare cases, fraternal twins can be born from two different fathers in a phenomenon called heteropaternal superfecundation. Although uncommon, rare cases have been documented where a woman is pregnant by two different men at the same time.
It's such a rare occurrence that medical experts have only been able to identify a few confirmed cases of superfetation in pregnant women. So, while yes, you could get pregnant while you're already pregnant, it's probably not something to worry about.
Is it OK to have sex during pregnancy? Your developing baby is protected by the amniotic fluid in your uterus, as well as by the strong muscles of the uterus itself. Sexual activity won't affect your baby, as long as you don't have complications such as preterm labor or placenta problems.
Your menstrual cycle is typically interrupted by pregnancy. This means when you are pregnant, you typically don't ovulate or menstruate. The body “switches gears”, so to speak, and focuses on developing the growing embryo.

Brace yourself…the first period after giving birth is typically heavier than normal because there is extra blood in your uterine lining that needs to be shed. You may enjoy easier periods due to physical changes in the uterus and cervix, although some folks experience stronger cramps.
A stillbirth is the death of a fetus in the uterus after week 20 of pregnancy. The reasons go unexplained for 1 in 3 cases. The rest may be caused by problems with the placenta or umbilical cord, high blood pressure, infections, birth defects, or lifestyle choices.
Stillbirth is the death of a baby before or during delivery. Warning signs may include bleeding or spotting. When the baby is in the womb, doctors use an ultrasound to determine if the heart is beating.
Not only is sperm safe, but there may be some benefits to having sex and contact with sperm before and during pregnancy: Sperm and vaginal sex can help induce labor when the time comes. Oxytocin, one of the key hormones involved in progressing labor, is released during sex, and orgasms mimic contractions.
You may decide to have your healthcare provider be responsible for disposition of the fetus. The provider may dispose of the miscarried fetus by burial or cremation. You can ask your healthcare provider if you want to know the specific method for disposition.
