When do you count pregnancy weeks from?

[Summer24]

My doctors and midwifes have always gone by my scans. I had a dating scan when i found out i was pregnant, i was 5weeks when i thought i was 7 weeks, then at 12 weeks it was confirmed how far along i was by the babies measurements and we were given an EDD.

I would be going from your scans as they can tell how far along you are by the babies growth and measurements.
