C.K.
I would like to emphasize what others have said about iron. I craved ice so much at the end of my second pregnancy that I couldn't wait to finish my drink to get to the "dessert." I brought it up to my provider and she basically blew me off. You should be persistent. After birth, I was very dizzy from the moment I first stood up until several weeks had passed. I also bled more than normal right after his birth and needed a pitocin injection to prevent hemorrhage. My son tested low for iron at 1 year old. I think it was all related even though I was never too low when they tested my blood.
