Hi. I had sex for a very short time. It was about only a minute thing. He thinks he didnt pre cum and he knows he didnt cum. It was unprotected. I didnt think i need a condom for somthing that short. It was my first time haveing sex. The next day my stomach felt funny i didnt know why. I guess it was just swollen from him, since it was my first time. This happend mayb around a week ago mayb a lil longer. And my period is due in 2 weeks now from today. And i got it today? 2 weeks early? And i also took a morning after pill the day after it happend to. Please help
