I've been on birth control for about 2 months, and each time before my period I get this irratation, reddness, and swelling around my vagina. I don't know why it happens bu the 1st time it happened it was before my period and I figured because I used a condom after not using one in a while maybe it was irritated, alos because my boyfriend used fire and ice by trojan -_- . It was irritated before I got my period and when I got my period it was basically gone but once it stopped it came back. When I seen my gyn about it I told her I thought it was a yeast infection and she said I do have a lot of discharge and gave me some cream and in a few days I was fine. And now I'm back to the same thing I don't know what it could be unless maybe its tied into the birth control or just a new thing with my cycle. Any information will be helpful.
