Me and my boyfriend had sex, well I wouldn't call it sex. He went in me for about 1 or 2 minutes then he pulled out. When he came out he had white chunky discharge all over him. (I know that came from me.) I looked,on my pants and saw a drop of white discharge on them because we were dry humping at first. That have to had came from him. He said he did not come in me. This happened on the day I was suppose to have had my period. A few days later I had it and was heavier than usual. Then the next month I had my period again it was very light and didn't last as long. I only had cramping and bloating on the first day which is not normal for me. I'm still waiting on my period this month. Could I be pregnant?
