Ethinyl estradiol / norethindrone
"Pricey ($10 off with discount card, but still around $75) but WELL WORTH it for me.  After some spotting in the first few weeks, I have had very little unscheduled bleeding, which is one of the more bothersome side effects I've experienced with other oral contraceptives.  My mood is stable and much improved relative to being on other oral contraceptives as well.  I have taken it continuously (skipped the inactive pills) for several months and have had no bleeding/spotting whatsoever, which I love, although I don't require a period to reassure me that I'm not pregnant since I'm that "perfect user" they refer to in the literature. Take it every 24 hours on the dot!"
