uterine fibroids
"I was so skeptical about these shots, scared to death of the side effects after reading posts...I could kick myself! My shirts fall past my waist, I always looked pregnant. Slight headache, took generic aspirin, did the trick, hot flashes, weird but no that bad. Cycle, had one regular (heavy) period then skipped. 
Overall, I was so satisfied, I just called and ordered my second shot (I get them quarterly).
Everyone reacts different to different types of medication...what works for others may not work for you but this did work for me.
Good Luck...Sorry for the grammer stuff was in a rush"
