birth control
"I started taking birth control pills a few years ago but after trying 5 or 6 different ones, I started taking OTC.  This is the ONLY pill I have tried that does not make me bleed through half the pack, clears up my acne to an extent, does not affect my mood, and makes my cramps basically nonexistent.  It is a miracle pill for me.  I think because it has varying amount of hormones each week that mimic your own cycle, it works better for many women.  I have not experienced any difference in my weight, I've started working out since I began taking this pill and have lost a little weight.  The thing I am happiest about though is that I do not have breakthrough bleeding."
