Hello! I Am Experiencing A Swelling On The Outside And

Hello! I am experiencing a swelling on the outside and very tip of the opening to my vagina after sex for the past week. I'm also feeling uncomfortably wet down there constantly. There is very minimal itching but mostly just an uncomfortable feeling. The discharge is pretty watery but accompanied by no odor. I have started taking oregano oil orally to help rid of yeast in case this is a yeast infection but it's still uncomfortable. Could this be a yeast infection or BV? I do not want to use Mobistar bc I have had horrible experiences with it. Adore.
