Hello, Welcome to HCM and thanks for asking your question. I would like to know that how much weeks you are pregnant and is there any other problem apart from itchy urethra, like whitish or fouly vaginal discharge, difficulty in micturition, etc. If i were your doctor, i would rightly suggest you to change the body wash, because it might be due to some sort of allergy to that stuff. I will also suggest you to do urine routine and micro examination and blood examination of CBC also. You can come back to me after having these reports and answers of my questions asked above, so that i can guide you further and properly. Also i would like to add that always use loose under pants and keep your private are clean with soap and water, everytime you go toilet. Also keep your parts dry. These symptoms may be due to allergy or fungal infection. So stop using your new body wash and you can take clotrimazole for fungal infection. Hope this will help you to get rid off your problem and you can come back to me anytime.
