1st scan ???

Nicola

So I got my bfp yesterday and called to make an appointment with my obgyn. That will be when I'm about 7 weeks. The have scheduled me for an ultrasound. Is this normal ? I'm from the U.K. Living in the us so I'm not sure if this is the norm and I will be paying out for lots of scans ?? In the U.K. You get first scan at 12 weeks then the final one at 20. Sooooo confusing. Don't want to be ripped off paying for stuff I don't technically need. Thanks ❤️
