You will find most places wont cover you after a certain point. But remember, this is for pregnancy related issues, not general cover. I.e. if you go into early labour, you wont be covered. But, if you fall over and break your arm, you should be covered. Albeit, I would also check with the insurance company before purchasing anyways just to get clarification.
There is another travel insurance topic somewhere, I'll try and find it and bump it up for you.
