I'm on my first pack of birth control, third week taking it. I had come back from school around 4 pm to realize that I had bleed dark blood, but very little and could barely even see. As well, I had sexual intercourse later that night with a condom around 7:45 pm and at 10 pm I noticed that I had been spotting and my boyfriend said that he noticed I had bleed onto the condom. It's a bright red and at first I noticed it being very little, then I woke up and I was able to notice it quite well; however, still very bright. Following that I am having very light cramps, which are barely hurting me. I was wondering if anyone could help by just seeing if they have had the same problems while on birth control or if I should be very concerned.
