Why is my vagina sore?

ok so at one point i didnt clean my vagina for 2 days [i know disgusting] and like it started hurting wen iwould touch the lower parts of the outter lips [which has like 2 little bumps on it that kinda hurt] and the inner lips kinda hurt when i touch then. This has happened before and i went to the doctor and she said it wasnt a yeast infection. Do u think its cause i didnt wash my vagina in 2 days and im not gonna skip days on keeping it clean anymore so do u think its gonna go away? Thanks c:
