Pregnancy dating: For women who have regular menstrual periods, dating for pregnancy is the FIRST day of your LAST NORMAL menstrual period. This can be tricky if you have a period that is abnormal for you and thankfully the ultrasound imaging that your OB doctor performs is much more accurate in dating your pregnancy.
