Conception Date

I have a quick question. According to my last ultrasound it dated me at 8 weeks 5 days. But according to my LMP which the first day was June 11th. That I am for sure about that. which would put me at 8 weeks.

I'm confused with my conception date. According to ultrasound my conception date is June 11, but that is when my period started. I'm currently 9wks 5 days based off the ultrasound from last week Is conception dates accurate?

It can be off by a few days b/c no one really knows the conception date unless you do invitro.  otherwise its a guesstimate based on your regular cycle.
sounds about right.  i am almost 8 weeks with lmp of june 24.
