So sore!!!

Amy
This is a weird question and possibly TMI...
For the past few days I've noticed my labia and vagina are sore, almost raw feeling! Had a swab taken at my last OB visit and no infection.  Wondering if it's from wiping a lot since I've been peeing so much, or possibly the soap I use.  Anyone else had this with pregnancy? I know she is head down and I have a lot of pressure because of that! I'm 32 weeks tomorrow and it feels like everything is getting more uncomfortable!
