High BMI and ultrasounds

It might also depend on where your placenta is. If you have anterior placenta you might even have your 12 weeks scan internally. But otherwise I think it’s about 12 weeks or so, as they want to see well. I did see some having abdominal already at 8, so I might be wrong :-)

Hiya, I have a high bmi myself and also had an anterior placenta last pregnancy, and I had a pretty clear abdominal scan at 10 weeks! Haven't had any scans yet this pregnancy, I'm only 8 weeks and have chosen to wait until the 12 week NHS scan this time round 😊 X

I’m a UK18/20 and only had abdominal ultrasounds in my first pregnancy, also with an anterior placenta.

I also had extra growth scans and never had any issues. They did have to send me for a walk to move baby once but that wasn’t due to my size.

Just a heads up, they will probably write something on your scan notes about “reduced visibility due to high maternal BMI” but nobody ever mentioned it as a problem.
