Soap after vaginal tearing

So I'm currently 12 weeks pp. I've had my check up and my OB said I was all healed up. I was told not to wash with soap because I'd see stars... Which with the pain I felt after having an episiotomy and tearing, I didn't doubt. Plus, I know in reality our vaginas are self cleaning and don't need to be wash with soap. Anyways, I started using soap because I need that extra clean feeling... Especially since I haven't had my usual wax lol However, I been using Dove sensitive skin unscented and I noticed a burning sensation that I never used to feel. Even when I use a tiny bit of soap and rinse with warm water, I still feel it. I'm wondering if anyone else has experienced this and if it eventually went away.
