"i was put on microgestin 1/20 to not only prevent pregnancy, but to prevent the severe cramps i had. it worked well by helping with the cramps and i had almost zero side effects but one- spotting. i spotted almost every day. i continued taking the prescription in hopes the spotting would pass, but it didn&#039;t. my ob-gyn then put me on microgestin 1.5/30 for a few months, to see if that would help. unfortunately, it didn&#039;t, so i stopped taking birth control all together. hopefully i can find one that works for me!"
