  • It is a little small, the rule of thumb is one centimetre for every week of pregnancy, so ideally you would measure 39cm at 39w. But it is totally normal to measure a little ahead or behind. It depends so much on how baby is lying, how much fluid you have, your build. I measured 2 - 3 weeks ahead most of my last pregnancy and my baby was not early, he was not big, it was just how I measured. Plus it can differ from Dr to Dr on how they hold the tape, where exactly they feel the top of the fundus is, where they place the tape on the pubic bone. It's just a loose guide to chart the rate of growth, don't get stressed about it.

  • Measurements don't really mean much of anything. IT could just be the way the baby was laying. I wouldn't worry about it to much,

  • Normal. As long as there is a pattern of growth, there's nothing to worry about. Fundal height measurements are only good at noticing growth over time and they are often a few centimeters off either way.

  • The range of normal is plus or minus 3 cm... so that's well within normal! It can vary depending on who does the measuring, and the baby's position, etc. As asaffell said, as long as there's a pattern of growth, all is well.

    And it may also be worth mentioning that at the very end of pregnancy, the measurement can even drop by a bit, because the baby's position shifts further down into the pelvis.

  • Maybe your due date is wrong?

  • normal. it could just be the position of the baby, or the baby is slightly smaller than average but still normal, or you might carry your baby a couple of weeks past the EDD :-)

  • normal. baby could've dropped and caused you to measure smaller. i wouldn't worry about it.
    oh, and if dr suggests an u/s to see about baby's weight, just remember that it's not accurate. it can be off as much as 5 lbs.
