5. Does a woman have periods while she is pregnant?

No

Explanation:

A period is when your body produces a layer of tissue and blood to protect the baby. But the period is when your body is like "oops, false alarm" and disposes of the tissue and blood. During pregnancy, the baby is kept safe by the tissue and blood, that is why women don't have periods during pregnancy.

If pregnancy doesn't happen, the body doesn't need the thick lining in the woman's uterus. The lining breaks down, and the blood, nutrients, and tissue flow out of the body through the vagina That it's the period. If a woman does get pregnant, the body needs the lining - that's why the period stops during pregnancy.
