When you go to the doctor do they always calculate how long you've been pregnant from the first day of your last period or do they have other more accurate ways to calculate it? I have my first appointment coming up and would like to know how they figure it out.
Hey 277250, yes they calculate from the first day of your last period until you get an ultrasound and then it may change by a week or two OR not. That is the way they did it for me anyways.
Congratulations and good luck!
