"I've been on this pill for almost 5 years. It has been ok. Except I got pregnant while taking it as prescribed. Didn't miss a day. Didn't take it late-or did I? If I did it was within a 15 minute window-it always is. Same time every day. I had a miscarriage but my obgyn says it had nothing to do with the pill...I have horrible mood swings too. My husband can predict my start date based on how insanely moody, aggressive and angry I am. It is always 5 days before I start that I am most insane. Always! The mood swings are so bad I'm considering getting off the pill altogether. Everyone's different. That's my experience."
