If you have private or group insurance at work or at school, you can ask your insurance company if the ultra sound is covered. If the answer is yes, you may do it at Clinique of your obstetrician.
I already went to a gynaechologist`s clinic. He gave me a reference and asked me to go to any hospital to ask for a ultra sound. I called and the result is 3 to 6 months on the waiting list. If there is a problem, I could have died then. Anyway, Shouqibao and Shanshan, thanks a lot! I`d like to try lasalle hospital. good luck to me.
