I got one at 8, 12, 16, and 20 weeks with my last baby. Most I know never get one past 20 weeks unless there was a concern.
Are you guys all in America?
I think it's common to do a last scan around full term to determine the size and position of the baby. I had my ultrasounds at 7 weeks (dating scan), 10 weeks (ER visit because I was bleeding with a threatened miscarriage), 19 weeks 6 days (gender and anomaly scan) and 37 weeks. I went into labor at 39 weeks :)
Depends on doctors I got one at 9 weeks, 20 weeks they didn't want to do another one but since I haven't gained any weight they did one at 32 weeks
Depends on your doctor and insurance.
With my first I had one at 7w, 10w ( because I requested genetic testing ) 20w and another at 30 something weeks but I didn't get any pictures for that one. With this baby Ive gotten one at 9w and I missed the genetic testing, got another at 20w , I haven't been scheduled for another ultrasound yet I'm 25w 1d. So I think depending on your insurance at the end of the day but I think the average is only 3 to 4 ultrasounds everyone else Ive asked has had the same amount unless there is something wrong than you get more.
Yes, i had one at 5 weeks then another one at 7 weeks, one at 16 weeks then one at 26 weeks to find out the gender and i got one on monday 39 weeks to see how big he is and if he can go through the birth canal
