The last month was a tiring time for me too and my iron level was very good.
Spinach is a wonderful source. If you're taking a vegan prenatal, chances are you're getting enough iron. Beets are wonderful for B vitamins and iron. I'm not sure how it works so well, but I'm anemic and just a couple slices every morning is enough to keep my blood count up when absolutely nothing else works. I even gave my gerbils a little everyday and they suddenly had a major growth spurt and tons of energy. I hate the taste of beets, but you can bet I always have it in the house anyway.
If you want tons of protein, soy foods would be your best bet. But you don't need as much as you think. The World Health Organization recommends about half the RDA after conducting a study on protein consumption in various countries. Plus the more protein you eat, the more calcium you need. Otherwise, it leeches the calcium from your bones and you end up with osteoporosis. So you don't really want to overdo it. Many beans and peas (other than soybeans) are a great source of protein without being excessive.
If you're still concerned about iron, you can also buy cast iron cookware (not the enamel type) which will ensure everything you cook in them has a little.
