I’m 31 weeks and a couple

Weeks ago I started feeling extremely fatigued and Light headed when I stand for to long just like crap basically.. so I went to dr and was told I was anemic but not enough to do anything about it basically within normal range for a pregnant person... this doesn’t help me as I have a 1 and 2 year old to look after so the way I’m feeling is making every day quite the struggle! So I want to just start taking a iron supplement anyway on top of what is already in my

Prenatal.. so can someone give me any advice on which on to take? Thankyou!! -btw my blood pressure is fine and my next Appoitment isn’t for 2 week.
