Protein is so important to get in our pregnancies, especially as you are approaching the second trimester. Our bodies need about 70-100 mg a day. Meat is not cheap. Here are some other inexpensive ways to add protein throughout your day: beans, lentils, eggs, yogurt, natural cheese, peanut butter, nuts. I've even tried beef liver this pregnancy and me and my family love it chopped and added to a bean and lentil soup which is super cheap to make.
