I recently had an ultrasound. Under the History section it displayed this:
LMP: 9/9/12
EDC:6/16/2012
No. Fetuses 1
Age 7w 5d
My blood and urine both came back negative, which isn't uncommon for my family, many of the women show up negative and baby is only detected via ultrasound. The ultrasound tech wasn't allowed to give any information due to hospital policy, but does No. Fetuses mean they detected 1 fetus? Or what?
