Go to Dr Adnan near Toysrus, he is the nicest man in the world, a good doctor, he has the most advanced ultrasound scanner in Doha and husbands are allowed in for the whole exam/consult. I have known him for 4 years, a very good doctor. You can just turn up on a Saturday morning, no referral needed, consult is about 250QR including ultrasound and written report and photos.
