Did you have low iron or anemia during pregnancy? If so can you tell me your symptoms?

If you had low iron or anemia during your pregnancy, what were your symptoms? My next appointment is in 2-3 weeks and I plan on talking to my dr. I think I may have low iron but not sure. The prenatals I’ve been taking do not have iron. I’m 21 weeks pregnant, for the past month I’ve been bruising soo easily. I am covered in bruises at all times especially on my legs, arms, and hands. I’m constantly freezing, I keep my thermostat set on 73-75 and I’m still SO cold that I’m almost always shivering even when I’m wearing thick pajama pants, a hoodie, and socks. I never experienced this with my last pregnancy so just wondering if this is a pregnancy thing or maybe my iron could be low?
