They would count the week after your last menses as like first week if I remember correctly. Hence, EDD will be estimated 40 weeks = 10 months.
So technically Yr embryo is what doc dated u minus 2 weeks. If u wanna know how many weeks is Yr embryo. Week 1 n 2 is nothing happenning. Lol
They will calculate based on your last menstrual period & your cycle (e.g 28 days). My LMP is 9 Jul, but today I’m 6W+
Yup. The doc use LMP to count. U can use flo to help u count too.
