Ethinyl estradiol / norgestimate
"I have menorrhagia (very heavy period bleeding). I have severe cramps. I was on Loestrin 24 Fe for a year, and I started getting my period twice a month! I started taking Tri-Sprintec a couple of months ago, and I haven't had my period at all, no cramps, my skin is clear, I haven't gained any weight either."
