Early ultrasoundp

[babycrazy42]

Hi I'm really unsure if this is the right place to post this but I'm worried because I'm curious as to know if any of you knew your day of conception and if your early ultrasound lined up to it?
I don't temp or anything I'm just curious because I thought I was 7w1d but my ultrasound says diff it reads
8w0d
M1 - 1.58cm
M2 - 1.59cm
M3- 1.60cm crl

Do you think she is accurate

TBH no-one knows exact date of conception - you can ovulate early, implant late etc.

However I would say at this stage baby is very, very small and hard to get exact measurements - so you may find it the measurement altered at your 12 week scan... but it's not that unusual to find out you are a week ahead or behind. At 6 weeks I was told baby measured 5 - by 8 weeks they said baby was 8w 2 days and questioned the initial scan xx

I agree with the pp. I know about when I o due to opk and my scan was a couple days off at 6, 8 and 12 weeks. The size of the baby is so small errors are easy to make and scan dates are considered +/- 2 weeks.
