abnormal uterine bleeding
"After the first 3 weeks it was amazing. The first 3 weeks I had horrible headaches and nausea but once my body got used to the hormones that went away and I had little to no side effects. I did have weight gain, but I've had that with all the BC's I've tried. I had very heavy periods with awful cramps that were making me miss school/work, and this made my periods very light, regular and with very tolerable cramps. Life saver. I haven't had as good of luck on the "generics" of the loestrin but it got very expensive and then discontinued. Oh, and also no pregnancy."
