I really do want one every visit or you at least hear the heart beat.. Maybe I can ask to only hear the heart beat

I think it depends on your Drs office. I've had one at every appt. I'm not high risk. But tomorrow she told me I'm not getting one because I'll be doing my glucose test.

I only got 1 ultrasound. It was the anatomy scan. That was the only ultrasound I got my whole pregnancy

Usually there's 3 ultrasounds for a healthy pregnancy, w/o high risk. First at around 8 weeks, anatomy scan around 20 weeks, & position check around 34-36 weeks.
