I had sex a couple days ago which was quite rigorous, in which I had to stop because it was hurting a bit, and after that I started bleeding and still am bleeding. We used condom and pill so Id be suprised if I had implantation bleeding. I also started pill straight away instead of missing a gap for my period, so could I be having my period even though I took the pill to miss it? I have been on the pull for 3 years and never really experienced this before. I'm a bit nervous because at first I assumed I was pregnant.
