In fact, that guideline about free over 50 singles dating days comes from Dr. The accuracy of determining the due date using LMP depends on regular cycles. All Genetics & Medicine Resources. All Genes & Expression Resources.

US-based dating was most accurate dating method pregnancy accurate (for 85% of predictions within 14 days) and similarly accurate at 20 - 24 weeks and at >24 weeks. Pregnancy dating by US, including those in more advanced pregnancies than currently permitted, is recommended since all non-ultrasound-based estimations of gestational age were considerably less accurate.
FH was less accurate with increasing obesity. LMP only works if the body is like clockwork. For instance, the EDD for a pregnancy that resulted from in vitro fertilization should be assigned using the age of the embryo and the date of transfer.
LMP, irregularities in cycle length, or variability in the timing of ovulation.
