Ultrasound?

Jessica • Im 26 and this will be my second pregnacy
Does anyone know if most doctors schedule a ultrasound besides 20 weeks I'm 37 weeks and I'm having a c-section on the 23rd but they never did an ultrasound I was thinking they do one next week but my doctor basically asked me if I wanted to come in next week which is a bit odd I'd think. Idk if it cuz I'm having a c-section or I'm going to call tomorrow and ask but I thought I see if anyone knew.
