1. It's Possible To Get Pregnant While Pregnant
Though it's very rare, some women have actually gotten pregnant with a second child while already carrying one. The technical term for this occurrence is superfetation and while it happens in some animals, it's almost impossible in humans as a pregnant woman's hormones are supposed to serve as a natural birth control against additional pregnancies. Of course, the word "almost" means that it does happen. Generally it occurs when the pregnant woman has released an egg a few weeks into the pregnancy, but before the first embryo has implanted and the hormones haven't completely kicked in to stop additional fertilization and implantation.
