So uncomfortable

Amanda • Sweet baby boy born 4/30/18! Sweer baby girl due August '19!

So, I'm 37 + 2 today and I'm so uncomfortable. I sit at a desk all day long and the last couple of weeks I noticed that it was becoming more uncomfortable and would get up more often to stretch and just walk. It usually helped. But today I just can't seem to stay in my seat unless I'm all the way back in my chair and leaned back. I'm seeing my dr twice a week at this point and have a Drs appt late this afternoon. But as of Friday he felt pretty confidant that I would make it to 39 weeks for my second csection. Just trying to figure out any ideas how to help when I have to be sitting to work...
