Okay my boyfriend and I had sex 5 times through 7pm-3:30am on August 1st. We did use a condom but only the last 5 minutes when he was going to cum. Then on August 4th we had sex twice. The next morning I had a small headache. So now it's August 6th. When I went to the bathroom and on my underwear I had brownish and white discharge. It wasn't alot, it was very little. Can anyone tell me what's going on. Were both 18 and lost our virginity's to each other. Sooooo I know it's not a STD
