abnormal uterine bleeding
"This is the best birth control I've been on. No weight gain at all. And it doesn't make it hard to lose weight. My boobs have gotten bigger. My skin is so clear I get compliments on it ( i used to have bad acne). And most importantly, no babies. I have sex with my SO without condoms so I know it works. I know exactly when my period will come every month.  That's a relief because I used to get my period anywhere from every 2-9 months apart.  



Only side effects is occasional nausea on the first week of each pack. And random headaches but that's not often."
