Finally pregnant !!! Need an opinion on something

So my SO and I are finally pregnant !! We went to our first gyno appt to confirm he asked me when my last period was and then congratulated us and told us to set up an appt for a sono at 6 weeks. He didn’t do any tests to confirm though, he said as Long as the tests said positive it’s positive. Hubby and I took about 7 tests in a week and a half span and all still positive but should the Gyno have done any tests or is this normal for a first visit ?
