Ultrasound frequency

Hi all!

So I have an ultrasound book with my OB at the 8 week mark but they won’t allow my husband in because of covid. So I’ve found a place that does allow husbands to come in, but unfortunately they’re not affiliated with my OB’s office, and my OB wants hers done at her location.

The ultrasounds will be four days apart, and I really want my husband to be able to be a part of it as it’s our first baby. Do you think having two ultrasounds four days apart is ok? I’m new to all this!
