birth control
"I'm 17 years old and I've been on Lolo for over a year now. The first few months were great, very little cramping and light bleeding, periods only lasted about 3 days. But in the past few months k have noticed my periods have been scarce and extremely light. I haven't had a normal period since January. Part of this is due to the fact that I had brain surgery at the end of January but by now I should be having normal periods. My period is about a month late now, I am not pregnant either."
