"i am 18 years old and i started this birth control almost a year ago. i was on a higher dosage bc but switched to this one because i was getting bad side effects with the other. although i didn&#039;t get pregnant, i wasn&#039;t completely satisfied. it did clear up the acne i had before i started using this bc. but i do have a way lower sex drive, i hardly want to have sex anymore. not only that, i haven&#039;t had a period in the last 5 months i have been on this birth control. i had consistent periods at the beginning, for 3 days and lighter bleeding than i had before. but lately i have had spotting during any week of the month instead of during my off week. i also cant take other medication, it causes spotting if i do."
