I'm 30 weeks pg with a very precious IVF baby. I live in a leafy area of London and walk 15 mins to the tube downhill so after snow freezes it becomes packed down ice on a slope. Last year I fell twice and injured my shoulder, so obviously this year I'm terrified of falling - plus I'm rhesus neg so any bumps mean a trip to hospital (and we don't have a car). Should I risk trying to trek in on Monday if it's icy or am I justified in staying home?
