Not sure where I was supposed to post this but I hope this is the place..

So I’ve been itchy .. downstairs .. for a couple weeks now and since I am 30 weeks pregnant I can’t really look except with pictures and when I look I have really white cm and it’s kinda lumpy but when I clean everything up it looks like I have a rash and I’m not sure if I should tell my OB or if I should find a primary doctor to look
