Unless your doctor has told you to up your iron intake I wouldn't take an additional supplement. It really does affect your digestive system and can be a real drag. After my first was born by a very complicated c-section I was against a blood transfusion and so became incredibly anemic. I was put on 900mg of iron a day. No, that's not a typo, 900. It was horrible beyond words. I was so afraid I was poisoning my nursling but my doc kept telling me it was fine to take that much. I took myself off that much iron after a couple of weeks b/c I couldn't take it anymore. I eventually recovered and after my second c-section I welcomed the blood transfusion and had such a better recovery! Anyway, it would seem that your prenatals would have enough. If you're curious you can ask for bloodwork to be done at your check up to see if your iron levels are okay. Enjoy your little one!
