abnormal uterine bleeding
"This might sound weird, but apparently this isn't uncommon for this specific birth control. I have been on it for about 72 hours. Have gained 4 lbs (which is good because I'm 30 lbs underweight) and have almost increased a full cup size with my breasts. I had horrible period problems. when I got the Apri a few days ago I was going on a 3.5 week period. After about 3 hours since taking my first pill, the period fully stopped. Very big fan of Apri!"
