Hi Sava -
I'm thinking nuts & peanut butter have a decent amt. of iron. Also dried apricots, prunes, beans, spinach, & lots of cereals are fortified with iron. Sometimes for snacks I eat deli meat w/cheese. Most lean meats are good sources of iron, and I know some people will tell you not to eat deli meat when preggo but I always have. I also get the precooked shrimp to eat with coctail sauce as a snack, and I believe they are a good source of iron as well.
I don't think my iron has been checked since my initial blood work at my first prenatal visit. I recall getting iron checks in my last pregnancies, but not this time, and at 32 wks. you would think I would be getting them. Anyway, I'm rambling...
