Due Dates?

[SSchreiber]

This is my second pregnancy and from the first day of my last period, my doctor put my due date at March 16th. I  had an ultrasound today and the ultrasound lady said I wouldn't be due until March 22nd, but said I was 6 weeks 6 days, so wouldn't the due date be March 20th? I'm confused. Has this happened to any of you?

I am almost 8 weeks my due date is march 16th when I first went in from the date of my last period I should have been 7 weeks but I was not quite 5 yet it's been confusing and my due date has only changed once by 2 days and my doctor said it will likely change quite a bit not by much though I was confused at first too.

I'm so flipping confused as well my doctor said that I won't be due until March 24 and I'm 6weeks6days and they said I conceived on June 30. But wouldn't that mean I'll be having the baby on March 21..I'm so confused ugh
