Itchy vagina but no STDs or yeast infection...

So I have been checked for STDs, all negative, no yeast infection, I haven’t changed any laundry or bathing products but I have been super itchy to the point I have ripped some skin and it just gets super sore. It itches on the inside of my the lips and right around the opening so bad, this has been going on for a couple months 😭. I am really starting to think it’s the birth control I am on Junell Fe. After I had my twins last July i took the mini pill since I was breast feeding and didn’t have an issue. When I stopped breast feeding I switched back to a normal pill, but I’ve never taken this brand before. Is it possible for the birth control to make my vagina insanely itchy? I’m so tired of the itch and the soreness!
