Due date estimation question!

Nini

I actually guessed on my LMP since mine are usually incredibly light and short and vary from 25-28 days cycles.

I got my first ultrasound yesterday (baby is great! 😍 thank goodness!) and was bumped from April 7th due date to April 2nd.

Would you keep the guessed LMP or accept the estimated due date based off the ultrasound in this situation?

*have not seen an OB, we were waiting for the ultrasound to find a midwife
