abnormal uterine bleeding
"I've been taken Seasonique for two years. Overall, I'd say that I love it - its nice not having to worry about a period every month. However, there are some side effects. I have noticed my personality has changed tremendously. I no longer get enthused about things, butterflies in my tummy don't exist for anything. I get really nervous and paranoid as well, and it started after I started taking Seasonique. My hair has also thinned out SLIGHTLY and not very noticabley around the deep end of my part, but its really not a big deal.  My periods dont start until the 4-5 sugar pill though! it's great! However, I'm switching to Sprintec because I'm sexually active and waiting for 2 months to find out if you're pregnant doesn't enthuse me very much."
