Bump on vag lip | UPDATE I WAS FINE DONT SELF DIAGNOSE

I have a bump on my vag lip and I haven’t noticed it before , I do normally shave but now I’m scared I would post it but ppl will probably make it worse I feel totally fine I’ve never had anything on my lip before, I literally just got off my cycle and the pads were irritating me badly i sweat a lot from work , and I’ve been wearing a pad for hours on I’m praying it’s literally from the pad idk what to do my doctor appointment isn’t until the 29th and now I’m scared the rest of my vag looks totally fine , could it just be the irritation from the pad rubbing against my v , part of me says I’m fine but the other part is scared
