11 weeks 1 day

I had a dating ultrasound today with a radiologist because I got pregnant this time after a miscarriage and didn't have a last period. My ob thought I was about 9 weeks but it turns out I'm at 11 weeks 1 day!! Is anyone else 11 weeks 1 day? Is our due date March 9th? lol I'm having trouble with calculating!
