I glanced through all of the comments below on Quasense and all of them indicated concerns about breakthrough bleeding. I thought I'd post a comment because I've been taking it for quite awhile now, after having been on Seasonale before this, and I haven't had a problem with Quasense at all. I was fine on Seasonale too but switched to Quasense when it came out because it's less expensive. I haven't had any breakthrough bleeding in quite a long time. If I had any, it was when I was on Seasonale and even then it wasn't much. I wonder why so many of you are experiencing so much bleeding in between. The only thing I do experience every month is mild cramping and it usually occurs around the time I would normally get my period if I had it every month. Other than that, I can't complain. When I'm off of it that 1 week every 3 months, I'm usually on my period for about 3 days and that's it. So for me personally, Quasense works fine. But everyone's body responds differently to medications. I'm sorry to hear that you are all going through this and I hope you find something that works better.
