Has anyone else felt like a Mack truck has hit them around the 17 week mark?? I was just starting to feel better but now I feel exhausted all the time. My blood work a couple weeks ago came back slightly low on iron, but I forgot to start a supplement (baby #4 here so I got busy with my other littles!). The last few days I've been feeling super dizzy and blacking out in the mornings. Today I had chest pains and chills and my hands and feet are freezing despite the summer temps outside. I don't know whether it's the low iron or maybe low blood pressure, since I always hover on the low side, especially when pregnant. I'm trying to up my iron intake through iron-rich foods while I wait on a supplement to get here (we live overseas so everything takes a couple weeks to get to us!). Anyone else having these issues??
