I got off the IUD a little over two months ago. My doctor had me start my birth control pills that day. I have the kind that only has three weeks worth of pills. Every month that I take them I don't have my period when I'm supposed to. I end up getting my period two weeks after I restart them. I don't know if I should stop taking them until my period ends and then restart them or what. But I don't think it's good for my body to be taking the pills when I'm on my period.
