My boyfriend and I had unprotected sex last Monday. Immediately after the deed, we both noticed blood stains on the sheets. Five days prior to that, my period started. Since my period usually lasted for 3 to 5 days only, I assumed it already stopped so my boyfriend and I went ahead with it. What seems to be the cause of bleeding? I stumbled on a couple of forums, most, if not all, gave the following answers: (1) cervical bleeding, (2) torn hymen, (3) rough sex [lack of lubrication, i assume]. I also had a brown discharge the day after (Tuesday), and still continues now (but not as much). Also, what are the chances that I may be pregnant? My boyfriend pulled out before ejaculating but I'm still a bit nervous. I took Nordette as ECP 13 hours after sex and missed out on the first dosage (took two instead of four as stated here: http://www.fwhc.org/birth-control/ecinfo.htm) so I really don't know what to expect. I happen to take the second dosage 12 hours after, though.
I hope someone could help shed light on the matter.
P.S: This is my first time having sex.
