abnormal uterine bleeding
"This was the first bc I have used, for my crazy abnormal periods and as a birth control. The first month was crazy, headache, fetigue, nausea, extreme cramps, but I decided to stick with it and eventually that went away. My period started on a Tuesday and ended on a Saturday and were way lighter, and I hadn't experienced normal period symptoms besides bloating. The second month I had crazy mood swings, followed by the month after that. Periods still came on Tuesday-Saturday, but I started noticing on my new packs, I had headaches, fetigue, nausea, etc.. My fourth and fifth month, I have had my period for two weeks. It would start on my 3rd week pill Tuesday, all the way until I had to start my new pack. I am shortly switching."
