First day of last period or sonogram?

Question

Hi ladies,

So if I calculate with first day of last period I am 10 weeks but baby measures (sonogram) at 7 weeks?  I just want the 1st trimester to be over and done with so I feel like going with the 1st day of last period lol 😄

Answer

You go by what the doctor tells you...

Answer

You go of ultrasound. Id ask for a second opinion because that's quite a big difference

Answer

Ultrasound is most accurate, especially if you have irregular cycles. Sorry!

Answer

Urghhhh poor you! I'm struggling with my first trimester so would hate to be told im 3 weeks behind what I thought :-/

I think it depends on you cycle lengths. If u have 28 day cycles i would go by ur LMP date.

I have 35 day cycles, so going by the date of my last period I would be 1 week ahead of what I actually am. I know for a fact that I am 1 week less because I had 2 UTIs in the month we concieved so we only BDed the once, so I know exactly when I concieved, which helped me pinpoint my EDD.

Hope that helps and fingers crossed you are 10 weeks! Xxx
