Vaginal Rash

Im 29weeks. A few weeks ago I noticed an increase in discharge. This lead to a a small rash on the outside of my vaginal area, looks like a mild allergic reaction with red, swollen tissue. It sometimes itch a little bit. I have been using pantyliners 24/7 since...

I will be discussing this with my dr. at my next appointment, this is however only 2 weeks away. Should I be concerned?
