Anemia symptoms

So I'm almost positive that I'm anemic but I'm taking iron supplements anyways because it isn't included in my prenatals. What are all the symptoms of anemia? I've been really pale, I've had awful tastes in my mouth and awful soreness in my legs. 
Edit: my doctor told me to take iron supplements but did not check my blood. But at my 18 week checkup I let him know my prenatals lacked iron and asked if that was okay and he told to go to my local cvs and pick up iron supplements so I didn't just go and get them randomly lol
