Arkansas couple Todd and Julia Grovenburg found out that they were having a baby and then discovered they were having two bundles of joy — but the babies aren't twins. An ultrasound revealed that a male fetus was conceived a full two-and-a-half weeks after the woman became pregnant with a baby girl, according to reports from local media. The Grovenburgs' obstetrician confirmed the case to Arkansas television station KFSM-TV.
The pregnancy is believed to be a case of a rare condition known as superfetation, or conceiving while pregnant.
It's very risky...
I have a friend and her mom was in the same situation and the younger baby unfortunately died because of that.
My friend still can't get over that and she thinks she killed her unborn brother.
