Am I pregnant?

Adriana
Early today my boyfriend and I were having intercourse and I started hurting in the lower part of my stomach and by hurting I mean in tears hurting, we stopped right away and just laid there. I'm still hurting that was like 6 hours ago. Is there any possible way I can be pregnant? We did have intercourse when I was fertile, and I am peeing like every 20-30 minutes and I having this tug in my lower stomach going down and in my back.
