So my period ended two days ago and usually I get a bit itchy and dry right after my period ends but it’s been really bad this time. I have to itch my vagina for maybe about 10 minutes and it burns after I itch it. I used tampons a lot during this period and I don’t usually use tampons so could this be an allergic reaction? I’ve never had sex so it can’t be an std. Is this normal? What should I do?
