I am going through a simular situation, I got off Depo-Provera in March of 2003. Directly after ending Depo, my cycles went irregular (which I have never been). Slowly, pain started occuring from sex to horrible cramps. Last April my doc realized that I probally had Endometriosis. So in late July 2006, I had surgery and found out I do have Endometriosis. I went on Lupron 2 weeks after the surgery and have been on it for 4 months. I had so many horrible side effects that were so much worse than the actual Endometriosis pains! I had everything from horrible night sweats which kept me up all night and hot flashes all throughout the day. They would hit me about every 5 to 15 minutes, they feel like your body temp raised 10 degrees! After all the surgery and the Lupron injection, my husband and I are fighting with the infertility! Since I also have annovulation we are having a hard time along with the painful/endometriosis pains during sex. I would talk to your doc to make sure you dont have Endometriosis. The number 1 symptom of it is PAIN. Good Luck I hope it all works out for you :0)
