Being nearly 32 weeks I find it easy to sit at my desk - I have a really good chair and a high desk so most of my belly is under the desk. I have a wireless keyboard so I move it quite close and I moved my screen closer as well.
I find that I have to sit up straight as I can to be comfy but over all no issues as yet.
However over the next 6 weeks of work that I have left Im in no doubt that I may encounter some issues as my tummy feels like it is growing rapidly dailiy!! Gawd help me in 6 weeks time!!

Youll be right as rain Ren!!
