Ethinyl estradiol / norethindrone
"I started taking Loestrin 24 Fe when I was 19 years old for 4 years. I have a slim body and I'm active. My periods are light and I don't get cramps or back aches while on my period and I don't have problems with acne. My periods were just very irregular. I would sometimes get my period the next month, the next week,  and even the next three months! And they would last like 1 week, 2 weeks and even 4 weeks one time! I was on Loestrin for 4 years because it didn't give me any negative side effects. It gave me regular periods and I never got pregnant. I stopped taking it because my doc told me they discontinued it! So she prescribed  me Minastrin 24 Fe. I looked up the reviews for it and didn't like what I saw. So I've been off bc for 2 years."
