End of pregnancy scan?


Hey moms for my first pregnancy I had a scan like 2 weeks before I was induced to get a estimate of what size baby was going to be when she was born and this pregnancy I have switched doctors and he does many things different but my last appointment is tomorrow and I will be getting induced this Friday (the 2nd) and they haven’t done the ultrasound and I’m not scheduled for one just my last regular check at my appointment tomorrow. Is this normal for them not to do it? And he says I’m right on track so should I go by my app to tell me about what my baby will weight??? I know they can be off because I was told with my first she was going to be big and she was only 6pounds 13oz but I would like to know a general guess and also this pregnancy it’s a boy and ik they say they usually weigh more than girls
