I had my 19 week anatomy scan on 10/12 and we left feeling confident that everything was okay since no red flags were raised by the technician. My doctors appointment is scheduled for 10/24. But today I got a voicemail from the doctors office saying they scheduled me for another ultrasound on 11/5. I’m 20 weeks today and I’m just now starting to show. Do you think this appointment is something to worry about or do you think the baby is measuring small so they want to keep an eyes on things?
