What is too low of a hgb level?

Kathryn • 17 and expecting a beautiful baby girl 🎀
I went to the doctor on Wednesday for my 24 week appointment. She told me that my iron levels were very low and I needed to work on getting them back up. She said my hgb was 9.5 and I am just wondering what it is supposed to be normally? I just want to know if I'm close to being at the normal number or if I'm far from it.
