3rd Trimester

Fundal Measurement

When your doc takes your fundal measurement are you laying down?  I feel like my bump is so much bigger when I stand or sit up.  It all spreads out when I lay down. 

I can ask this at my appt tomorrow, but is the measurement in cm supposed to be = to how many weeks you are?  For example, I will be 31 weeks, so should I be 31 cm?

Re: Fundal Measurement

  • Yep, I am laying down when they take it (though I'm much bigger standing up).  You are supposed to measure at whatever week you are at.  For example, I'm 28 weeks and I'm measuring 28cm so I'm right on track!  Smile

  • from your belly button to your fundus + 20 = how many weeks you are measuring

     

    so if you're measuring 7 cm above your belly button- you are measuring 27 weeks  (10 cm above would be 30 weeks)

  • Laying down - and it doesn't matter that your bump flattens out, they measure the height of the fundus, not the roundness and the height doesn't shrink when you lay down:)
  • My doctor has never done a fundal measurement...what week do they start this?

  • They are actually measuring the size of your uterus.  She will push on the your pubic bone..be careful it hurts...then feel around for where your uterus stops above your belly button. I am actually measuring three weeks ahead!
  • They are measuring the height of your uterus, so standing wouldn't work. They need to be able to feel where the top of your uterus has grown to at that point. They always measure while laying down.

    They started mine around 20 weeks.

    mine started about 28 weeks

  • I read that it is in cm equal to the weeks you are +/- 2 cm is on track.  They measure me from my pubic bone.  i.e. tomorrow is my 30 week appt so I should be measuring between 28 and 32 cm...
  • Yup, laying down and they started at 28 weeks. But it's never hurt when they do it....
  • I've been measured at every appointment, starting very early in the pregnancy, and always laying down.  I was right on track until 37 weeks.  I've measured 36 since week 36, but Midwife said something at last appointment that it stops increasing at 36 weeks, and she's not concerned.
