Can you shed your uterine lining and have a normal heavy period if pregnant?

No, it is not possible to shed the uterine lining and have a normal heavy period if pregnant. During pregnancy, the fertilised egg implants itself into the uterine lining and begins to develop into a foetus. The hormone progesterone is produced in high levels during pregnancy, which helps to maintain the uterine lining and prevent it from shedding. As a result, women do not experience menstrual periods while they are pregnant.
