24 week appointment

Yesterday's appointment was, as expected, largely uneventful. My weight was up a little more than would be ideal, but the reprimand was pretty mild. I forced myself to go to the gym yesterday, which actually felt good. I've been exceptionally gym-lazy lately, so perhaps it will start a new habit. I also ate a real dinner (i.e. not cereal or snacks), which I rarely do when P works late, which happens very infrequently but happened last night and will again tonight.

The doctor commented that I looked run down. I told her that I had never really gotten that burst of energy that people claim comes with the second trimester. I also mentioned the whole fainting on the bus episode (and a few near-fainting episodes before and since), since I had spoken to the nurse and the midwife at the time. She decided to send me for bloodwork. Note that I told her at my 16 week appointment that I have a history of anemia and that I was feeling run down, and she said then that they normally don't run another round of bloodwork until 28 weeks and that I should try to ride it out. And so I did. Needless to say, yesterday's bloodwork came back this morning and my RBC, HGB, and HCT are all low. Shocking. She hasn't called yet to tell me whether they are low enough to justify doing anything and if so what. I'm going to have to resist the urge to say I told you so.

Anyone know at what point one's RBC, HGB, and HCT are sufficiently low to bother with supplements? I know that the "normal" range is lower for pregnant women, but I had trouble finding a pregnant-person range online anywhere.
