I'm vegan and I take my prenatal, calcium and iron supplement, and a vegan omega 3 DHA+EPA supplement. I generally eat boatloads of dark leafy greens (kale, spinach, chard, collards, etc), plenty of legumes, nuts, quinoa and amaranth, tons of fresh fruit, nut milks,etc (whole foods). However, this first trimester has been rough- constant nausea and no appetite whatsoever. I still force myself to eat relatively healthy, but blech! veggies are among my worst aversions right now. Once I start to feel better (hopefully in the next week), I will resume my pre-pregnancy diet and just increase the amount of protein I take in (legumes, nuts, pregnancy-safe protein powder in my smoothies). Like MindUtopia said, I just eat what my body tells me to eat. From what I understand, the embryo/fetus initially just feeds off what you have stored up (which is why a healthy balanced diet leading up to pregnancy is so important). Just take care of yourself and you and your LO will be fine!
