HELP! TMI. Rash!

Help! So I'm 32 weeks and about 2 weeks ago, I noticed a rise in my discharge so I started using my panty liners more than normal.. I noticed after 2-3 days that I started getting itchy down there and when I checked, I noticed a bad rash.. I just thought it was from the discharge and panty liners, & I didn't shave for the first time ever since my magnifyin mirror didn't arrive in the mail yet, all this combination was irritating my skin probably (this has never really happened to me). So I just thought I would keep the area dry, apply diaper cream etc and it'd go away.. I've used calendula diaper rash cream that's organic.. Then desitin.. Nothing has worked! It's been 2 darn weeks and nothing is working. I looked at symptoms of a yeast infection, it can't be a yeast infection because my discharge isn't cottage cheese like, looks just normal discharge. My husband and I have normal sex and there's no pain or discomfort whatsoever. No bad odor either from the discharge. We leave for our anniversary trip next week and we're going to a natural hot lagoon! What am I going to do?! HELP! Should I go to the ER? This is awful! 😩
