So after I ran out of birth control (sprintec) I forgot to pick up my prescription. I have been on the pill for almost 3 months now. I only started taking the pill because I have PCOS and had only had one or two periods in my life. After starting birth control my periods were regular. My last period was about a week and a half ago which was normal but today I started bleeding again.  Also not to give TMI but I had some rough sex a few days ago. I have been sexually active the entire time I've been off the pill and I've probably missed about a week or so of birth control. Could I be bleeding from the rough sex? Could it just be from taking the pill/ not taking it? Could it be implantation bleeding? Should I be concerned? Sorry if this is confusing I tried to explain the best I could! If anyone has any guess to what could be happening please comment!
