Help please!

Around 2-3 days after I finish my period I get super itchy and dry on my vagina. The skin cracks and bleeds as well sometimes! I thought I was having an allergic reaction to pads so I switched to an all natural brand and while it has helped it’s still pretty bad. I’m on the pill so most of the time I skip my period to avoid this issue but when I do have to bleed I dread it! I have gone to the doctor and she recommended me thrush cream and I started to use it but it actually made it worse and I used it for the time she said and the way she said. Now I have been trying some stuff obviously because it’s not a nice feeling but I was just wondering if anyone else gets this or if they have any tips or tricks!! I’m desperate to figure out a way to help!!
