I'm a young girl, still in school and I made the mistake of having un-protected sex. My last period was at the end of the second week of July, and today is the end of the second week of August. Now ideally I would have gotten my period today, but I didn't experience any symptoms and my period did not come today. I know I should give it time, but I'm incredibly worried.
When we had sex, he pulled out and ejaculated on his stomach, but I've heard that it is in fact possible to become pregnant from pre-ejaculation, even though the chances are low. The fact that there are still chances really worry me. I don't know how to calm down about this, and I know that if I keep stressing about it, my period will be late regardless.
What should my plan of action be? What should I do if I am pregnant?
