SMALL LUMP INSIDE VAGINA AND UNSURE IF MY VAGINAL OPENING LOOKS NORMAL???

I'm getting extremely worried theres something wrong with my vagina. ive had sex with a new partner without a condom in may ish time. is this cause for concern? i felt a little tiny sort of change where a slight diff textured bump appeared inside my vagina but nothing major. im aware of the sensation at my vaginal opening as if it has swollen?! is this actually normal i cant remember what my vagina really looked like previous to me checking today... I also randomly had some brown discharge today and after feeling the small growth thing in my vagina. i could have just been off with my timing on my pill.
