Ethinyl estradiol / levonorgestrel
"I've only been on it for a month but so far no negative experience. I have been spotting here and there for about a week or so but my actual period was so short compared to how it normally is! My periods are usually 6 to 7 days long and I experience heavy bleeding but on BC, it was much lighter and lasted about 4 days. I did experience some nausea the first week but none after that. No noticeable weight gain yet so so far, it's been pretty pleasant."
