I know there are some pregnancy related rashes, I would call your doctor and see if the can maybe prescribe a cream for you
There is a thing u can get caused by pregnancy severe itching of hands feet face etc. The only way of stopping it is telling ur dr getting a special medication.. good luck I know that horrible itching feeling.
I had simular itching and rash (I'm almost 38 wks, this started around 35wks for me)...mine has been the stomach and thighs tho. My dr said mine is called "pregnancy pops" a form of heat rash that some pregnant ladies get. I just use Eucerine to help relieve thw itching and it seemed to help a ton! I would still bring it to your dr attention to treat :) good luck
