When did you first see midwife/ GP?

This is my first pregnancy, and I'm a little bit lost at the moment. When I first discovered I was pregnant (at 4 weeks) I rang my GP surgery to ask them about their procedure. The receptionist told me to come in and fill in a form to be sent off to the midwife. I did this the same day. I am now 6 weeks tomorrow and have not heard from anyone. Should I have seen a GP or midwife by now, or at least had an appointment scheduled? What have your experiences been? 
Thanks for your help!
