Some women will deliver on their due date, others before, and others after.
The body is not on a clock counting down to delivery; natural variation will introduce uncertainty.
I don't know about you, but I know about ten people who's OB had them go for a C-Section because the ultra sound was measuring their baby "too big"..then their baby turned out to be either small or completely average in size.
I think ultra sounds are obviously a great piece of technology, but they are not 100% accurate and a lot of times they make mommy's worry more than they need to. Martha Mommy to Keaton 12/22/07 EDD Absolutely go with the ultrasound! before I started BCPs, my cycles were always 32-35 days. This cycle, we were moving, buying a house, and I was weaning my daughter. I would have had another 50-something-day cycle had I not conceived.
Midwife prefers to use my LMP to calculate my due date, which puts me at July 25.
Ultrasound on 5/14 dated me 14weeks, 0days with CRL 82mm with EDD 11/12.
Could the birth control not have worked in Jan, the embryo lived through the withdrawal bleeding, and the fetus has continued to measure small throughout the pregnancy? According to this period date, the most likely date of conception would be around 14 days after the period, that is around the 19th of February.
Ultrasound has intrinsic error of upto maximum 5 - 7 days, so the probable dates of sex would have been a week before or after the 19th of February, but in NO WAY as early as January 18th.
When an ultrasound is performed, measurements of the head, abdomen, thigh, and amount of amniotic fluid are done.
These measurements are computed automatically in the ultrasound machine’s software.
