I am starting to see a pattern. every time I am on my period or come off my period my vagina becomes very itchy and irritated and the skin around the vulva starts to peel off it has worked it's way down to my buttocks and it burns.. I have been tested for STD and came back negative I did come back positive for chlamydia about a month ago and was treated. And have had protected sex every time. I don't think this is a yeast infection and I cannot go get checked up because I'm currently on my period. I have tried getting checked up in the past times it has happened to me. but by the time I make it to my appointments the irritation has gone down. and all they have told me is that it's a possible reaction to my body wash or underwear ect. I have changed my soap to unscented soaps and my under garments as well. nothing seems to help.. I have been reading online and it sounds like it could be jock itch I'm not sure.. But I defenetly know that something is not right down there if anyone has an idea of what it might be please share with me. I am desperate and in need of help. Thank you
