I've usually measured four weeks ahead from the second trimester onward. I have a very short torso and my babies don't nestle into my body but stick out like tight beachballs. 
So I measure 'ahead.'
Anyway, throughout my pg, I've been remarking to dp that this baby is doing such-and-such a month earlier than the others did. Of course, I didn't take my own cues and have been steadily wondering what's going on with the baby seeming so mature for my dates.
At what I thought was 32 weeks, I measured 41. I had not measured for a while, but had done so the month earlier and I measured 6 weeks ahead which did have me wondering but I thought that it could have been just the baby's position that time. I do my own prenatals and it wasn't a matter of holding the tape differently or anything like that. But when I measured over a few days' span and blindly of course, I still came up with 41cm.
Then when baby dropped two days ago (with a clunk), my measurement went down to 37cm and this is the pattern that my pg with ds3 took at the end- 4 weeks before birth-, though he was a 46 weeker.
Anyway, I looked up my calendar and found that I had not done a pg test the month before I thought I had become pg because I had a two-day bleed (incidentally that stopped very suddenly), so I thought there was no need, though I did think it was rather strange since I usually have five or six days of bleeding. I waited five weeks from then to test (because I missed my period that time for sure) and it was positive. But now I think I was pg the whole month before so that I am 36 weeks now, not 32.
AAAAAH!!! We were already cutting it very close with renovations before the baby is born, and now we have a rush on. And I am not terribly good at rushing just about now.
Anyway, the baby has dropped and I'm 3cm dilated. Not 32 weeks at all, besides that this baby is way too big to even consider him/her 32 weeks. I have been suspicious for several weeks because I can easily feel the length of the baby's spine, and now the crown to rump measurement fits a 36 week marker (and I've been noticing a rather large disparity between the average c-to-r measurements and my baby for several weeks).
My belly skin is very thin, so I can grab feet and before baby dropped and was turning around still, I had to look up the size of the avg. head and again, my baby's head was four weeks-worth bigger.
So, I'm further than I'd anticipated and have to do twice the amount of work I expected to be doing in the time I likely have left.
Just venting, and being amazed at the same time.

I know most of us would LOVE to skip a month (or several!) ahead, but I also know that by the end of my pgcy, we'll be knee-deep in moving, and I could NOT stand to lose time at that point.
