Until recently, there was very little science to back up the concept of pregnant women having “baby brain,” some experts even claimed it was a myth. However, a new study in Australia found that’s it’s a very real thing. And it’s also very common, affecting 4 out of 5 pregnant women to some extent. Baby brain gives women moments of confusion, forgetfullness, or difficulties concentrating. These symptoms are most likely to occur in the third trimester and the only people who really notice a difference are the women themselves. (Photo: DrugAbuse)
