abnormal uterine bleeding
"So I started this pill and was excited but had to stop right in the middle of the pack.  I mean out of nowhere, there is a burst of bleeding.  I went to the bathroom and it's like my period snuck up on me and it was almost 2 weeks before my period is due.  There was lots of clots and brown yucky stuff.  On top of all that my moods were really crazy. I would be lying in my bed and would feel like crying and then be okay the next moment.  I have only been off now for two days cause I just couldn't take the crazy mood swings and the bleeding anymore.  I also noticed a great deal of fatigue and even that has changed even after just 2 days off of loestrin. It's not worth it and I cannot wait for it to be out of my system."
