I am only 26 weeks...but baby measures 27 and have been having the same problem. For the past 3 days I have barely felt him move at all. I haven't even felt him move since yesterday morning and it is driving me crazy. I hate calling the Dr on a weekend, but am starting to consider it. I have a doppler and his heartbeat is within the range it should be so I am hoping he is ok.
I do wonder if he maybe just switched positions or something though.
Hope everything goes ok

I am sure your little one is probably just getting big and has less room, but I totally understand your concern.
