My Ob always rang me back within the hour. With my last pregnancy, I had some bleeding at 13 weeks whilst I was down in Mornington for my in-laws 50th Wedding Anniversary. I rang David's paging service at 9am on the Saturday and he called me back within 10 minutes. He arranged to meet us in his rooms at St. Vincent's at 12pm for a scan (everything was fine). I was very impressed with his care.
