I would definitely get your iron levels tested. It is very common in pg to be low. I had mine done a few weeks ago and they came back at 8 and should be 11 or more or something - can't remember, but my Dr recommended an iron supplement, Ferrograd C - the vitamin c helps with absorption. Yep, I was feeling yucko, just thought it was because I had entered the 3third tri but it all made sense when she told me my iron results and now i am feeling better. Definitely try and get your iron levels tested, if you can get a bit more energy to get through this last bit of the pregnancy just by taking a tablet then it is worth it.
