When do you get bg ultrasounds?

I have my sequential screening at 13 weeks and 4 days.  Will my next ultrasound be at 20 weeks?  I keep reading about 16-18 week ones.  What are they for?

Mine isn't until 22 weeks this time.  I had to work with DH & the doc's holiday schedules.

It all depends on your Doc's schedule and how the office runs. My last OB appt was at 14w, so my next appt at 18ish weeks will be when we get the big u/s (even though we arent finding out the sex). I did not get an u/s at my 14 week appt. My office only typically does two u/s...one at 18-20 weeks and another at 30-something weeks.

At our office it is an 18 wk u/s.  But I had it at 18 wks with DD and she was actually a week and a half younger and they couldn't tell the sex because she wasn't developed enough yet.  So now I wait until later if they let me.

It really depends on how your OB appointments fall.  My "big" u/s was last week at 17w2d.  We're team green so we didn't find out the sex but it was awesome seeing our LO.  My next appointment isn't until I'm 24 weeks!!

I had mine in my 19th week but I think it's normal to have the big anatomy ultrasound anytime in week 18-20

My OB office does the big ultrasound between 18-22 wks.

My BIG u/s with my OB will be when I'm 20 weeks...but I went to a private ultrasound place last night and basically had my big u/s then
