PLEASE HELP, HERPES OR NO???

I had sex with my partner, which it was rough and unprotected. I had then noticed a lump under the skin in my groin area which never hurts, even when pressure is applied. A couple days while shaving I noticed my vaginal area was sore. The next morning when using the bathroom I noticed a small cluster of liquid filled blisters. They didn't hurt or anything. I figured it was irritation. A couple days later I had been at an event which required continuous walking for around 6 hours. This had irritated the blisters and more formed. They had burst and due to open sores they were painful when touched or rubbed by clothing. From walking so much the lump in my groin was a bit bigger and had a little sense of pain. The next day the lump no longer hurt. The blisters were still pretty painful but much better than the day before. The next day the blisters barely hurt at all. I even forgot theyy were there until it came time to use the restroom and I seen the area to remind myself. I never had any other symptoms of any sort. The blisters just came, were very uncomfortable, then left. They were there for maybe a max of 7 days and are now almost completely gone. Could this be from shaving, rough sex, irritation??? I don't feel as if it is herpes but it had a similar look but no symptoms of it. I have an appt to get checked but i'm still very worried.
