Health-care providers define the stage or length of pregnancy differently than many people might think. Logically, one might imagine we represent a pregnancy by how much time has elapsed since conception.Instead, we most commonly date pregnancies from the first day of the last menstrual period (LMP).Every pregnancy is unique and your baby will come when it's ready.Be sure to talk to your health care provider about your due date.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.If you deliver on your due date, your baby is actually only 38 weeks old, not 40.Please remember that your due date is only an estimate.
Also, when providers all use the same LMP date, we are using one system that provides a standard convention.Midwife prefers to use my LMP to calculate my due date, which puts me at July 25.Honestly, I think I'll end up somewhere in the middle.Anyway, I'm not particularly worried about it, just curious to know if anyone has had this happen, and what the outcome was.
Was your LMP due date more accurate, or your ultrasound due date? I also go to a midwife, but I've done a great deal of research on the cons of ultra sounds...A normal pregnancy can last anywhere between 38 and 42 weeks.
