I don't normally post but I just need advice here.

Ok so according to my date of conception I'm due on 11th of March making me 34 weeks pregnant but my first ultrasound that I did dated me a whole week behind and gave me a due date of the 18th of March (mind you, the hospital that I did the ultrasound at is known for their errors but was my only choice at the time)

With that being my first ultrasound my midwife is going with the date of that ultrasound though I know my exact date of conception.

I did two other scans after the first one(including 20 week anatomy) and both measured 2 weeks ahead

What I really wasn't to know is how many weeks am I really, do I go with my date of conception or do I go with the first ultrasound? I'm confused.😩
