abnormal uterine bleeding
"I started this pill to only have 4 periods a year.  I don't need the Birth Control because my husband is "fixed". I was like clockwork every 28 days, but my period would last 7 horrible days.  I had major bleeding, clotting and cramps.  So, I thought this would help with both the flow and amount of time.  I started the pill 8 weeks ago, since then I have been bleeding (enough to wear a pad) for 4.5 of those weeks. My breasts are super sore, and have grown a cup size. I have had cramping for most of the time.  I'm going to stop because it's causing the very thing I'm trying to eliminate."
