I'm 31 weeks, do they do an ultrasound for the third trimester?

not unless your measuring ahead or something is wrong

usually they don't unless they think something may be wrong. only reason I got 2 was cause first I was measuring small and the did a growth scan and the second was cause I didn't pass a nst

My dr did at 36 weeks. Got to see how much she is weighing. And they also check your fluid levels 😊

I think it depends on your pregnancy. I go tomorrow for my last ultrasound and I will 37 weeks and 5 days. but I'm high risk and have to be monitor.
