abnormal uterine bleeding
"Out of the 3 pills I have taken (the others being Microgestin Fe and tri lo sprintec), Trinessa is probably the best. Microgestin caused not only constant constipation and the worst depression I've ever experienced. I switched to Trinessa and these problems lessened within the first month. Trinessa did give me some nasty forehead acne and mood swings, but these also disappeared relatively quickly. My only real complaint is that until the 5th month on it, I would spot for a week straight before my placebo week. My flow was pretty heavy, but no terrible cramps accompanied it."
