"this is my first birth control. before i started taking lo lo i had heavy periods and really bad cramps, so bad i had to leave school sometimes. lo lo has changed that for the better though! i no longer have cramps and i either don&#039;t have my period or it last for only one day. this pill is like a little miracle! love it! only problem i have had with it was when i got off an antibiotic i had small cramps for the 1st month back on."
