I've Read A Few Stories About Women Who Were Pregnant But Still Had Their Periods. Can This Happen?

Believe me, I've been googling this SAME thing for the past couple of days. No, it's not possible to have your period and be pregnant at the same time. Your period is your uterus shedding its lining. During pregnancy, the embryo has attached itself to this lining, so if you shed it, you're not pregnant! That said, women do sometimes experience bleeding during pregnancy, but it's not a period.
