Travelling for work


I am due mid Feb (first time Mum) and I am hoping to work as close up until my due date as possible as I would prefer to spend my time off with the baby afterwards. My job involves travelling to meetings across the country (UK based). My work location is home based in my contract but travel is expected. At the moment I try to stay over in hotels when I can just due to the general pregnancy tiredness. Do you think it is acceptable to tell work that after Christmas I will be working from home unless a meeting is within an hour of my home address? I can still work remotely and dial in to meetings as required. I'm just really concerned about going into labour and being far away from home.
