I recently lost my virginity (about 3 or 4 weeks ago). It hurt a lot but there was no bleeding. Since then I have had sex quite a few times and there has not been bleeding or pain. A day before my period came (it was supposed to come that day but it is often late) I had sex in a new position and it was slightly painful at first but by the end it went away. The next day it appeared that my period had began, but the blood seemed lighter in color and did not flow freely. I did not experience any pain. Believing that I had began my period, I started on my first ever dose of birth control (Ortho Micronor). I have been taking it daily, as directed by a doctor, since then. The next day it appeared that my period had stopped, but that evening it came back full swing. Normally my period lasts around 4 days. It is generally quick and easy, but sometimes comes with extreme stomach cramps. The next day (3 days after my period had presumably began) I experienced those extreme stomach cramps, but they went away. I have had no pain since then. It is now the 6th day of my period. Normally my period would be over by now. I am not experiencing any pain, but the blood appears to be similar to the blood I had on the first day and not similar to my regular flow. Is there something wrong? What should I do?
