First US not until 18-20 weeks 😩

Had my first appointment last week at 9+6 and all is well! I asked my doctor when first US would be scheduled (was expecting 12 weeks), but she told me my one and only ultrasound won’t be until 18-20 weeks. Anyone else in the same boat? My last pregnancy I received 2, but it was following a MC so I’m wondering if that warranted the extra US (so that insurance covered it).

I’m in USA (PA).
