Hi, I am two months pregnant, and I have been getting often hungry ever since. But all of a sudden in the past two days I haven't felt hungry at all... is this something I should be worried about?

Probably not... your appetite will fluctuation throughout pregnancy. Eat what you can, but there is no need to force yourself. Try grazing throughout the day... eating small amounts of healthy foods here and there. As long as it is not prolonged there shouldn't be a problem. If you wanted a bit of insurance, drink one of the healthy supplement beverages available, such as Ensure.
