so I got my first ultrasound at 5w4d and everything looked great , of course I am going to a free clinic . but they want me to come back in a week after when I'm 6w4d to see if the baby is growing and there is a heartbeat . now I've read some other people's post on here saying their doctor won't give them an ultrasound until 12 weeks so is it safe to get an ultrasound at 6w4d ? just curious .
