Paying for an ultrasound...

Alexis
The naval hospital here won't give you an ultrasound until 12 weeks. So, I found a fetal imaging center that offers a "peace of mind" package that's $50, it includes an ultrasound with a dvd, lots of print outs, and a heart beat teddy bear. They will see me next Thursday at 8 weeks! They told me to drink some water before they see me, any tips or insight as to why? How much water? Cold water? How soon before seeing them? Lol
