I have been taking aviane as birth control for exactly two months. It is the first type of birth control that I have ever been on. I take it for regulation of my period as well as to prevent pregnancy. Three days before my period was scheduled to come this month the area right around the opening of my vagina became extremely itchy. I tried as best as I could to keep my hands away and the itchiness went away when I got my period. My period ended last night however and today the itchiness has once again returned. I know my boyfriend does not have any stds and I was tested when I began on my birth control and came up negative, plus he is the first and only man who I have been sexually active with. We have also only had unprotected sex one time, and not a time close to the start of the itchiness. I really have no idea what it is, but i'm worried and don't know what to do about it. If anyone has any ideas I would really appreciate to hear back from you.

Thank you so much.
