Ok, it all started with sharp pains in my right ovary and that turned into sharp pains going up my whole right side, then I got my period and bled heavy for 2 weeks. After that I had a foul smelling discharge. Now I got my period again and its been 2 weeks and its still going on with very painful cramps. What could be wrong?

Oh and it also hurts whenever I have sex

Certainly check with your doctor. Could be a cyst or perhaps endometriosis.
