Bump on Vagina.

Ty

Recently , I just shaved . Everything was good up until the hair was growing back. I had a couple ingrown hairs and then I had another , which I thought was a ingrown hair . But it’s fill there , can’t find any hair follicle to remove and it’s very disturbing to me . I tried to cut it Open and it bleed . No pus or anything and it’s painless. What could this be ??
