Requesting not to get a sonogram?

So my doctors office does a sonogram every single apt. It’s awesome that I get to see the baby every time I go, until I get that bill. I have a new insurance with a crazy deductible, so I am paying almost $200 for each sono. I already had 2 sonograms and I am only 14 weeks and looking at a $600 bill. I know some offices don’t do sonograms every visit, so would it be weird if I requested not to have it when I go??
