Unless you're high risk, then no they likely won't do another.
Usually the ultrasound where you find out the sex is the last
It's the last until you get further along and they want to measure the baby.
With my first my last was when we found out the sex and this pregnancy I get one every month since I have gestational diabetes the Dr likes to keep an eye on growth
Yes. Normally 20 weeks is the last one unless there is a medical concern and they feel another is necessary.
No you'll see the Dr more often, but not get another ultrasound unless your high risk.
I only got one ultrasound and that was for gender and measuring out baby.
