I've had confusion my whole pregnancy. I originally thought I was due March 1st due to my last period. I went to the DR and wasn't given a due date but was told the sac was measuring bigger than the baby. I went back a week later and got a confirmation of pregnancy with a due date of March 9th. My Dr left the practice when I was 20 weeks so I went to a different practice. We never discussed my due date, but every paper the nurse gives me says 13th so I asked today and they told me according to the first ultrasound it's the 13th so that's what they will leave it. I know the baby will come when he wants to, no matter what my due date is, but it makes me feel like I'm going backwards! The good news is that I got to see my little boy today to make sure he was head down, which he is!
