when tracking your pregnacy do you use the day day you concieved or the first day of your last period. when I do the day I conceived it puts me at 14 weeks 5 days if I use the 1st day of my last period it puts me at 16 weeks 2 days
I use 1st day of my last period. it's the same due date my doctor gave me as well.
I've always used the due date my OB gave me
you do 1st say of last period. thats how doctors calculate it
