I got my ultrasound report back.

The baby is measuring at 6w0d

The sac is measuring at 6w6d

The fetal pole they got was 83.

Today I got a call from my dr and he wants to wait till October 3rd for me to come back in so at that point he can hear the baby on the hand Doppler…

I got a positive ovulation test on the 24/25.

Positive test was august 5th

Drs confirmed my pregnancy on the 10th.

So these dates make since where the baby could be 6 weeks instead of 9?

My due dates changed from 4/13 - 5/01
