Which due date are you using?

Question

I guess Drs use your LMP to calculate the gestational age and due date but I know the date of conception which makes my baby 4 days younger than the age my Obgyn gave and due 4 days later. My obgyn explained they only use LMP and that there was no need to change anything. Just curious what you ladies use to calculate? Thanks!

Answer

Lmp, which is right on with my dating scan.

Answer

The dates on all my ultrasounds have lined up with the gestational age calculated by my last menstrual period.

Answer

I used my scan. Doesn't matter anyway! Chance of delivering on your due date is super low. 🙂

Answer

My LMP lines up to the day with my ultrasounds, but if they didn't I'd go by ultrasound.

Answer

Usually they use your lmp and your dating scan

Answer

4 days doesn't mean jack shit. Pick either one. Easiest to go with the doctor.

Answer

Dates line up pretty well with my LMP.. baby was only measuring 1 day behind at my last ultrasound so therefore my OB told me we will still go off my LMP.

Answer

On my scans, baby is measuring 5 days behind. And my doctor still goes off the lmp date. They're all just a guess anyways because the baby's going to come when it's ready. And that can be before or after. So lmp is just standard.

Answer

Honestly everything lines up exactly to the same date. My LMP, my dating scan, my anatomy scan, and measuring my uterus even.

Answer

i go by lmp
