Is there a way that you can go some place just to get an u/s? I really like my doctor and I don't want to go behind his back, but he only does an u/s at 20weeks. I'm 12 weeks and there is a possibility I might be having twins and I would really like to know for sure. I don't know if I can go to an ER and get one done or not.. but my husband and I really want to do an u/s to see if it's one or two babies and my doctor won't budge on it. Any ideas?
