Ethinyl estradiol / levonorgestrel
"I have been taking Seasonique for almost 3 months now and for the most part am very satisfied with it.  The only downfall I've found so far is weight gain, around 5-10 pounds, which doesn't seem like much but to a smaller person it makes a huge difference in clothes fitting. Normally I could get this weight off pretty easy but so far that's not the case.  I haven't made it to the end of the first pack yet so I'm hoping this first cycle I have isn't as bad as what some of these comments say.  I'm on week 7 and in the last week noticed a tiny bit of spotting, not enough to use a tampon or even a liner.  So far so good best I can tell.  This is still way better than having a period every 28 days."
