Hi ladies,

I am interested in your anecdotes about the accuracy of fundal height measurements in circumstances where height has measured rather large throughout the latter part of your pregnancy.

I am apparently just over 34 weeks along. I had no idea as to dates when I found out I was pregnant (cycle a bit all over the shop) had a dating scan at around the 8 week mark. My best guess, and it really was a guess, at that stage was that I was perhaps 6 weeks along.

Anyhoo at my last ob appointment (right on 33 weeks) I measured 40 cm. I have consistently measured 6 cm ahead of dates since about 28 weeks.

I understand that there are a few variables which affect the accuracy of such measurements including weight, if you have had other children, if you have had a caesar or if you have gestational diabetes, or if the babe has an identified problem such as kidney problems or some digestive problem (oesaphogus) or mouth problem (eg cleft palate.

This is my second babe, the first was delivered by caesar at 42 + 1 weeks after I failed to progress on an induction. I understand from reading that the c section can affect how my uterus presents on a fundal height measurement.

I do not have gestational diabetes and the babe otherwise appeared ok at the 20 week scan.

I was overweight at the start of the pregnancy but have not put on too much weight (just on 11kg). I am retaining a bit of fluid which I did last time too.

So I am off to have a scan early next week to see what's happening in there. I am happy to see the little one again but now a little nervy about what might I might be presented with. I understand that the later in the pregnancy a scan is taken, the less reliable it can be compared to early scans insofar as measurements are concerned.

So I am interested, for those who have historically measured fundally "large" what was the outcome?

Was your ob seemingly guided heavily by fundal height analysis in circumstances where you measured large?

Thanks in advance!

Cheerio Belinda.
