Multiple pimples on one labia?

So I did a combination of things the last few days and I was freaking out when I got home from work. I was on the tail end of my period, so I used boric acid suppositories to correct my pH, and that next morning I went for a 5mi run. I had a pad so you can imagine all the moisture I put my poor vagina thru. Fast forward to yesterday, I come home and looked at my vagina bc I was feeling uncomfortable at work and there were 4 large pimples! I freaked out thinking it was herpes or something because I slipped up and slept with this guy I was talking to without protection. The pimples are on the left lip only, and they don’t hurt that bad except for the one by my vaginal canal. Ha anyone had this many pimples down there at once? I’m trying to stay calm because I’m out of town and I don’t have my doctor here smh Also I shaved 6 days before so I wasn’t sure if they’re just ingrowns coming thru.
