I had a lot of people tell me they had their period while pregnant & they have healthy kids. could it be true?

Yes: It is not common but it does happen. But of you are pregnant and bleeding, go see your OB right away.

Nope!: It is not possible to menstruate while pregnant. Anyone who says so doesn't understand the physiology and endocrinology of menstruation, that's pure myth. Many many women have vaginal bleeding while pregnant, that's normal: but it's not menstruation, and not your period.
