Belly ultrasound? How early?

Melissa • February 22nd!
My midwife only does a 20 week scan, and we found a place that does ultrasounds just for fun. We are just dying to get a peek. We went ahead and paid for a time slot, but they only do abdominal ultrasounds. Has anyone had an abdominal ultrasound this early instead of an vaginal one?  I know it won't be as clear but I'm dying! At the time of the ultrasound we will be 6 weeks, 6 days.
