Talk to Gynecologist on Gyne Related.

I am 19 weeks pregnant. I visited my doctor on 26th of april. In ultrasound everything was normal. I can now feel baby movements. But from one month i am having vaginal itching and rashes that come and go on its own. One day i get severe rash and after that otherday its normal. Then again after one or two days, i get rash. Due to rash the area gets inflamed. I am also having a white but very thick vaginal discharge. Urine is completly normal not associated with any burning or pain. I am currently not using any medicine for this. I also want to know if it cause any complication or harm to fetus as its more than one month? My next visit to doctor is due after a week. But i'm in tension thats why I want to know.
