Heavy period on birth control

Kimberly

I was taking the pill for 3 months and then quit for a month and got my first normal period about 3-4 weeks after. On the first day of that period I started taking the pill again. When I was on the pill the first time my withdrawal bleed always came on the 4 day of inactive pills and would only last about 3-4 days and very light bleeding. But now it’s super heavy bleeding with heavy cramps. It’s already the 5th day of bleeding and it doesn’t seem to be slowing down at all although the cramps are gone now. Is this normal?
