iron supplements

Just was curious if anyone had the issue with iron? Every time I took the iron supplements I was getting exhausted and was vomiting. I ended up telling my obgyn this and she had me switch to no iron prenatal vitamins. I noticed a difference after the switch because I was able to do more and eat a little more. Now at 37 weeks I'm confused because I only have a couple weeks left before my baby's due. What to do? I have my appointment tomorrow so i can ask my obgyn. -Amanda
