I just lost virginity a couple of days ago and have been bleeding since then, mostly when I urinate or after sex. It's very light bleeding though. I also notice very light brown spotting on my panties every day. I am worried because we used protection only from the middle of the intercourse and I am afraid that I may have become pregnant, even though my BF had a condome when he came. I'm experiencing dizziness, slight crams and bloatedness. My period is not due for another week. Please advise, whether my bleeding can be caused by loosing virginity or if it's a sign of pregnancy. How early can the pregnancy symptoms be detected?
