wrong due date?

[kkinley]

I got pregnant by monitoring my discharge to tell when i ovulated. According to that, I ovulated right after my period ended. During my pregnancy they have had my due date calculated by the date of my last period despite me telling them I ovulated early. Well, at my 20 week ultrasound baby was measuring weeks ahead. Since then I have been measuring 2 weeks ahead as well and so have my symptoms. What should I believe?!

Did they give you an estimated due date when you got the 8th week ultrasound?

I did get one at 8 weeks and they said I was "on track" but didn't say if baby was big or small. They say as long as you don't measure over 2 weeks ahead or behind, they typically don't do anything.

I wish you had gotten a due date in an early ultrasound, like at 7 or 8 weeks.  Because babies do grow at different rates from the average, so a 20th-week ultrasound could just reflect the baby growing rapidly.
