Hi, I am in my 15th week of pregnancy and will be travelling to the US on a B1 / B2 visa for 45 days (13 September 2013 to 27 October 2013 both days included). At the time of travel I will be in my 19th week of pregnancy. I will return to India during my 26th week of pregnancy.

Is there a maternity insurance I can buy for the above period? If so what is included and excluded?
