Well, I'm 19 years old and lost my virginity on the 18th. I took a test after four days and it came out negative. I know its too soon to know if I am or not. But I need some questions answered. First, it was unprotected sex, he pulled out, but I'm worried about pre cum. I know they say there's no sperm in pre cum unless they have ejaculated prior to it. And I know that there's no way he could of that day cause he was at work all day and I picked him up when he got off and was around him until it happened. I haven't had any symptoms, and I'm not suppose to start my period until January 11th. I plan on taking another test in about a week to make sure. Should I get on birth control even though I don't plan on being sexually active? I feel ashamed :( because I wanted to stay pure until marriage and made a huge mistake..
