"i&#039;m 17 years old and i&#039;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&#039;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."
