"i was on a different birth control beforehand and i had every side effect possible, so my doctor switched me to microgestin and i&#039;m so glad she did! i haven&#039;t had a single side effect since being on the pill! i used to get terrible cramps and even after taking the pill for a month the cramps were completely gone. the only thing that happened was that my breasts got bigger, which i&#039;m not complaining about!"
