Okay girls please someone explain what does it really mean to measure 1 week ahead ? Does it mean anything? I was supposed to be 11 weeks and I measured 12 ? Do I go by the count from the 8 week ultrasound or the 12 week one? I have two apps one with a due date of feb 12 and the other with the due date of feb 18 !! I’m so confused !!
