Panoramic blood test

when did you ladies have your blood drawn for this test? My doctor said they usually have patients wait until 12 weeks to have the test done but I know you can do it as early as 10 weeks. He said I can go at 11 weeks and it should be fine. Today I'm 10 weeks, 4 days. Should I just wait until I hit 11 weeks to do it? I'm curious when other people got their blood drawn
