So i am on marvelon birth control, and ever since i have started it whenever i have sex my vulva hurts. It's not like an excrutiating pain, but just kinda of a stinging, rug burn type feeling, and it annoys me when i have sex because it feels like i'm burning down there. I don't have a yeast infection or any of that, but i was wondering if birth control can cause this? The last time i went to get my birth control they had to give me the generic brand for they ran out of my kind and my vulva pain stopped, and i could enjoy sex again.. but now that im back on marvelon it started happening again! I was just wondering if there was any way that birth control could cause that? thanks !
