Anemia in Pregnancy

Al
I had a WIC appointment today and the nurse checked my iron levels. I have had issues with low iron occasionally in the past, but with my first pregnancy it was extremely high. With this pregnancy, I'm 32 Weeks and 2 Days. I've been getting 
extreme headaches, I'm exhausted most of the time, my heart condition (which I really rarely ever have trouble with) has been bothering me. My hemoglobin test came back 10.1. The nurse didn't really say anything about it other than that it's low. She didn't give me any advice or even tell me to talk to my doctor. I have an appointment with my doctor later this week, so I'm not overly concerned about it right this minute, but I was wondering if anyone else had this problem and what I can do to help raise my iron levels. Keep in mind, I do not eat meat of any kind and I haven't for years.
