Soooo. I had my period 1 weeks ago. My periods are usually 2 months apart. I just started bleeding again 2 days ago. It's all black and there are a lot of clots... its not a ton of bleeding its on the medium/lighter side, but im curious as to why this is happening. I did miss a couple days of birth control while i was on my period and I did have sex on those days. I've never had this before. Any suggestions? Please help
