Advice please

I'm 27 weeks pregnant so I've had all the basic labs done to test for stds etc but i recently started getting a burning feeling down there I've also had a lot of discharge my Dr told me it was a yeast infection but I have no itching/lumpy discharge plus its been this way for almost two weeks I have something that I thought was Fordyce spots but I'm starting to think it may be something else 🤷🏼 I'm going to ask her about it tomorrow but I thought that they checked for everything i don't understand why they wouldn't considering the fact that it could put my child in danger some people may not speak up like I am doing.
