Question

Ok this may sound a little weird, but wondering if anyone is experiencing the same thing, I am 21 weeks and I am having issues in my vaginal area, it is very sore and red. Almost like I have a rash or something, almost feels like chaffing. I have used powder, tried diaper creams and it's gotten a little better but still bothering me. Has anyone else had this happen? I don't to the ob for 2 more weeks for my check up and I will ask then, but just wondering if anyone else has ever had this issue?!
