endometriosis
"I took the shot for 6 months, I had issues that I could tolerate.  Such as vision change, the injection would shot pain a crossed my lower back. Well it's been 8 months since I had a shot took me 2 months before my period returned. I recently started experiencing pain in my belly button, vision was getting worse, mood swings, the end of April period was bad then 2 weeks later had another one. I was ready to have everthing removed, I had gave up hope of having a baby... So out of the blue I missed my period and now I'm 5 weeks  PREGNANT! !!!!!!! I wish everyone good Luck and hang in there!!!!"
