Help ! Idk what to do

Hello :) so I’m 14 weeks pregnant, and I have a pimple looking bump near my inner thigh near vagina area , I wanted to try tea tree oil because I know it’ll dry it up quick but I was told to avoid essential oils , also my pants and underwear keep irritating it when I walk, so I want to do something about it. I told my OB about it but she said it’s not related to the pregnancy and she wouldn’t worry about it and to just put a warm towel over it 😑 any other remedies I can try that are safe? I’m so desperate for this to go away !

Also I have no STDS I been checked
