The Doctor Moved My Due Date Up

by Catherine

The doctor moved my due date up when I was pregnant. I was pregnant with twins by in vitro fertilization. My fertility doctor had my due date for the 13th of the month. Once I was released into the hands of my regular obstetrician/gynecologist and she gave me my first ultrasound she also moved my due date up to the 8th of the month.

That seemed out of whack to me because if you are doing in vitro shouldn't they know for sure when you are expected to deliver. She told me that it could be off a few days because of the time it took for the implantation to take place or it might have been because the fetus was measuring at a growth rate for a baby 5 days older, if that makes any sense.

I have been told by a few members of the medical community that twins often develop faster than a singleton pregnancy. Somehow the body speeds things up a little because it knows that most twin pregnancies don't go to the full 40 weeks gestation. And that was true. I went in to labor at 34 weeks.

So to all expectant mothers just know that you cannot predict the exact day your little one will arrive. All you can do is be prepared for it whenever it is.

Changed Due Date NEW
by: Anonymous

A changed due date can happen for a few different reasons. Maybe you didn't remember the exact first day of your last menstrual period correctly. Or maybe you have an irregular period and was not sure of the day at all.

Most times when your pregnancy due date is changed it is because the baby is measuring at a bigger size than it should be for your progression or gestation. As the baby grows they can measure the crown to rump size as well as the head circumference, and these numbers are pretty standard for all pregnancies. So if you are fetus is measuring the same size as most fetuses who are further along in days or weeks then that is probably why your estimated due date was changed.
