The discharge is brown and have no smell, i wouldn't say there is blood because im far from having my period. the vaginal blisters aren't exactly on the vagina but on the soft. skin between my vagina and the butthole. i had a yeast infection recently?

Vaginal infection: There's no way to accurately judge the cause based only on this description. Some features strongly suggest genital herpes or yeast infection, maybe both. Brown discharge often means infection, including gonorrhea or chlamydia; or maybe blood, indicating spotting between periods. Any of these symptoms by itself needs professional attention, and you have several, possibly serious. Get care ASAP.
