i think i have an ingrown hair

hi! i have a quick question, okay so when i shave, i know i shouldn't but sometimes i shave inside the lips of my lady parts and this morning in the shower i felt a very very tiny bump from where i shave sometimes... it doesn't hurt at all when i press on it and nothing is coming out. it doesn't have a head either. it itches slightly but i know ingrown hairs itch bc i get them all the time. any thoughts? it just kinda scared me a little and i had to think about it!
