Advice.. Kinda scared..

So, about a month and a half ago, my bf and I had kinda an accident. When he came, it was on my stomach and some of it got... Down there.. And I had my period 2 weeks after so I never worried bout it. But now being almost 2 months later, my boobs hurt, I m sleeph all the time, and my emotions arw all over. So, I'm kinda putting pieces together, and I'm a little (a lot) nervous. Am I being overdramatic or something? Help!
