New mommy to be

Hi there, got my bfp on Saturday, and I have my first ob visit this upcoming Tuesday.

Is there anything I can expect? Will the do an ultrasound? The only thing they told me was that they were going to do a pregnancy confirmation and I was so overwhelmed I didn’t think to ask if anything else was going to happen? Does anyone know? If my timing is right, I should be 4-5 weeks
