Anemia during pregnancy

I am 29 weeks. I recently got blood work done as my OB wanted to test my iron levels along w glucose. Glucose came back fine but my iron levels scared me a little. According to the NIH anemia during third tri is hemoglobin below 11 and hematocrit below 33 so I read this as on the literal verge of anemia.

I got very sick during 1 and 2 tri (nausea) and my prenatals made me puke. I switched to a gummy prenatal w out iron and just try to eat iron rich food. I obvi found that it wasn’t working with these results. I took an iron supplement tonight and I’m sure my doc will call tomorrow but in the mean time…..Ive worried myself as everything I see about anemia and pregnancy says things like preterm birth, stillbirth, excess maternal bleeding etc. can someone who can relate calm my nerves?
