Measuring 2 weeks behind

Kailey

According to my LMP I should be 9w1d but at my first ultrasound today the lil babe measured 7w1d.

I have irregular cycles. And I’m almost 99% sure we conceived May 4. Is this normal?

Have you measured 2 weeks behind according to your last LMP? Or is it okay because I have longer cycles and conceived May 4....

Thank youuuu
