Good Day I Hope I Can Get Help. My Vagina

Good day
I hope I can get help. My vagina skin us peeling off soon after my period. This is the second time it has been happening. It peels off to the point that it bleeds. I went to see a Dr the first time I experienced this. She said I have an std. I was given meds for it and injection then I never had sex again since then I got my next period and still experienced the same problem. It wasn't first time I have been facing the same problem and I'm given antibiotics for an std but I still get watery discharge and discomfort still afterwards. No examination has been done. I'm just getting diagnosed by explaining my problem to the doc and checking the discharge. I'm worried I have something more serious coz it doesn't go away. I did all the hiv tests. I'm negative. I always had a genital skin problem even when was younger. It will peel off now and again and I got discharge when I was very young. I don't know if recurring problems I'm currently facing may be related to my past too.
