Last month about the middle to the end of my period my vagina started itching and burning. It burned to urinate at times also. There were never any bumps or sores or anything like that. It was just red mainly from scratching. I treated myself with a 3 day yeast infection kit that didnt seem to do anything. This itching and burning lasted about 8-10 ten days. I'm not sure what to think since there were never any bumps, sores, or blisters. Yes, I'm sexually active so I know its possible it could have been herpes. I've been tested for all curable stds and they all came back negative. Is this a usual sign of herpes...meaning no bumps, sores, or blisters? I really dont want to go for blood work so opinions please!
