Hey, how are doing now? I hope you feel better. Well, first of all let me tell you something if anything hurts for whatever reason you should go to the doctor. Second of all it depends on how long ago you & your bf had sex. If its been a couple of months and you haven't gotten your period more than likely you are pregnant. Take a home pregnancy test and find out. If you take the test and it comes out negative then you could of have a few pulled muscles, but if you are not sure that the test came out right then all you can do is go to the doctor.I hope this helps you out. Keep me posted.
Sincerely,
Mrs. Butterfly
