What Causes Cramps Near Cervix While Having Vaginal Intercourse?

About a year ago, I had an abortion. Sex with my partner is still painful. While engaging in vaginal intercourse, I get painful cramps near my cervix. Occasionally, I feel cramps near my uterus and ovaries. The pain is getting unbearable. Since the abortion, my period also brings sharp, nauseating cramps. I d thissomething to go to the doctor for or I d this just how it s going to be?
