Does starting the birth control pill make your period heavier?

Answer 1

Starting the pill does not usually make your periods heavier. In fact, most women will find that their periods will become significantly lighter. This is due to the action of the pill in the body. The pill works by preventing ovulation (no egg released), increasing the thickness of cervical mucus (makes it harder for sperm to travel), and decreasing the thickness of the endometrial lining (harder for an embryo to implant). Since the endometrial lining is thinner this generally means lighter periods.
