Ok so five days ago I had sex with my boyfriend we've been going out for a year now, it was my first time having sex. We used a condom and we only had sex for about 30 seconds, because I just wanted to know how it felt so we did it quick. He did not *** at all , but then the next day I had this weird brown blood come out of my vagina, and five days have past and now it brown blood with some red blood, I have cramps and normal period symptoms. Its weird because my period is supposed to be next week not this week. Could I be pregnant, I'm freaking out !
