birth control
"I was on LoSeasonique for almost a year. The first few months were great, some spotting every now and then but nothing major. About 2 months ago, I took a pill one day late. Consequently, I have been spotting for the entire two months. My gyno tried everything, putting me on a weeks worth of estrogen and then a regimen of taking multiple pills a day for week. Nothing worked. I've been miserable and bloated and have gained a few pounds. 

Before this, I really liked this pill. If you take it, make sure you take it at the SAME time every single day. She said pills with this low dose of hormones are more likely to to do this. I'm currently having to switch to another pill just to make the bleeding stop."
