Ethinyl estradiol / levonorgestrel
"Started it two months ago and the only problem i have had with it is the fact that I am off my period for a few days and I start back up on it for a week and again the next week, been this way since I started. I have had regular periods with other birth controls and I was regular when I wasn't on the pill. I personally don't like having a period every other week and I take the pill everyday at 9am."
