I am 19. I have been having sex with my bf since 2 years. Today, for the 1st time I got a little blood while doing it. First, I thought it is my periods, but then after washing my vagina, the blood just disappeared. I have no pain and no other symptom at all. The blood just disappeared. I even tried to finger myself to find out if there was blood inside, but nothing. I and my boyfriend haven t had sex with anybody else ever. We lost our virginities with each other. Hence, the chances of STD are negligible. I have no medical history. But yeah, i did eat an emergency contraceptive pill in july. But that was 2 months ago. Is something wrong with me?
