My vagina has a small bump that I think might be an ingrown hair and I have no signs whatsoever of an std?

Depends on sexual hx. If you have been sexually active with new or multiple partners, you may want to get a std screening done or have an ob-gyn evaluate your vaginal area. However, if you feel you have no risk factors, you can keep an eye on this lump and see how it changes over the next few days to weeks.
