how long does the anatomy scan last ?

Ba

hello I just want to know how long does the anatomy scan last ? I'm 22 weeks 3 days today and im getting my anatomy scan in a bit. what should I expect ?

Update: I only lasted 10 minutes in there 😐 really disappointed. I thought it would be at least a good 20 minutes but the u.t gave up soon saying that that's all we were gonna get. He said so far everything so good. Still enjoyed seeing my prince.
