is something wrong?

After i have sex is it normal for my overies, uterus, or cervix (i'm not specifically sure which one of these it is but i know it is one of them) to feel sore. Even hours afterwards or is something wrong? P.S. i'm a very small woman. I'm 5ft and 90 lbs my vaginal canal is very small as well. Literally everything about me is small. Could this contribute to the soreness??
