"i took aviane for almost two years before switching to mirena (which i love, by the way.) i never had sex without a condom while on this bc, but it seemed to do its job. i never got pregnant. i did, however, regularly experience the withdrawal bleeding (a &quot;period&quot;) consistently a few days before the placebos began every month, but it was predictable so i didn&#039;t mind. i took the pill at the exact time every day. i just don&#039;t think the hormones were quite strong enough to hold back my bleeding. basically aviane worked alright for me, although i did notice some minor but more frequent bouts of depressive episodes that were very short while on this bc. i had a lot less acne while on aviane, but small flare ups a day or two before my period."
