typically when does your OB want to hear from you?

I did. But the girly answering the phone I don't think has a clue - she told me to call back after I was a week late with my period - well I'm calling Thursday - close enough! lol but I have to talk to the nurses station - I'll explain everything to them and let them decide. The OB doesn't even want me to do the intake appt until after the US.
