"the first time i started using birth control i started on a different pill which i can&#039;t remember the name but stopped after the second month due to crazy mood swings and worse cramps during my period. when i went back to the doctor i got prescribed sronyx and i have been using it for three months now and i have yet to experience a bad side effect. i love this pill! i highly recommend it . no headaches, cramps, or mood swings.
