Measuring small with twins??

atrain

I'm almost 29 weeks along  with twins and at my ob appointment today the dr. measured my fundal height and I'm measuring smaller than I did at my last appointment 4 weeks ago.  I have a sonogram scheduled for Friday to check the babies growth.  Has this happened to anyone else?

I measured smaller during one of my visits. But I noticed that the doctors started and stoped at different spots and thought that was why.
