Thanks for using the forum.
Due to the fact that you are sexually active, it is possible that you are pregnant. However, you would not be experiencing any pregnancy symptoms at this point. Your abdominal pain is most likely not related to pregnancy. If the pain continues you should see your doctor to make sure that there is nothing else going on.
I hope that this helps.

Just wait till you're supposed to get your period. If your period doesn't come then, go buy a pregnancy test.
