I recently stopped taking the depo provera birth control injection. I did not get my period yet. I went off of it about 3 weeks ago. About the last two weeks my breasts have been really tender. I have slight lower abdominal pain in a u shape along my whole front and when I have intercourse it gets severe, I get really hot at the time, get nauseated, and feel like I may have diarrhea. What is going on? Am I pregnant? Could it be ectopic pregnancy? Please Help
