I don't see why they would unless your high risk
Same here for me too. On Saturday I'll be 39 weeks & my last ultrasound was when I found out the gender at 19 weeks & I am getting induced this Monday due to swelling and my baby measuring big. I wish I had more. With my first I had an ultrasound once a week because it was high risk.
The last time i had an ultrasound it was in my second trimester and i was 20 weeks , im now 39 weeks +2 days. The doctor said as long baby is doing and growing fine there's no reason to have one.
yew normal only to know the gender and then only if the need to chk in something or if u order one and pay for it like a private place but if everything is normal they dont need to
