This is mostly for my own documentation...
I'm looking forward to my next prenatal - to seeing what my caregiver thinks of my fundal height. I've been consciously practicing self-palpation for my last several pregnancies, and I'm regularly feeling the top of my fundus at my belly button. On me, that's ~22-23 cm. Generally, your fundus corresponds to the number of weeks along you are, and for me that's held true through 6 previous pregnancies.
Here are some possible reasons I found on babycenter.com for measuring "large for dates":
• Your due date is off. (Nope, don't think that's possible)
• You have looser abdominal muscles than most women as a result of an earlier pregnancy. (rofl!! I've had 6 earlier pregnancies - ya think?! But my abdominal muscles have been looser than normal for 10 years, so I'm not thinking this is it)
• You have uterine fibroids. (This is a known side effect of estrogen dominance, so I'm not ruling it out. However, looking at the list, pre-pregnancy I had no symptoms of uterine fibroids, so I'm not super concerned about this)
• You're carrying twins or more. (Twins do run in my mom's family...)
• You have too much amniotic fluid. (I suppose this is possible, but honestly, what I'm feeling does not feel like amniotic fluid to me)
• Your baby is positioned high above your pelvis, which might be the case with a breech baby or if you have a placenta previa. (This early in the pregnancy, I don't think these would really be issues)
• You have a bigger-than-normal baby because of gestational diabetes. This condition is known as macrosomia. You may need to be tested to rule it out. (Given my history, the list of risk factors, and my current condition, I really don't think this is it. And my urine's been "great"! lol)
So that's the fundal height report. Any reasons you know of that aren't listed here?
