I am 32 weeks pregnant with an obvious large bump and wear a baby on board badge. I commute at rush hour and usually every time I get on board the tube there are no seats available. I see the people sitting glance at me and then look pretend and pretend they haven't noticed. I've just endured another journey standing the whole way feeling tired and dizzy because no one will offer a seat. Yes I could ask but it would feel uncomfortable why can't anyone offer? Surely all the people sitting can't be hiding various disabilities?
