my last period started December 9, 2017. I was due for af on the 8th of January. I have taken several pregnancy test and they came out positive! :) I have also confirmed pregnancy with a urine test at the doctor. They did blood work and the blood work only shows I am 2-3 weeks pregnant? I guess I’m confused on what that means when I should be 4 weeks and a few days when going off the first day of my period. Does the 2-3 weeks mean after conception? Please help clear this out. I am a first timer so I’m pretty new to all of this! :) thank you so much!!
