Anemia in third trimester

Ashley • Welcomed our first child, a baby girl, into the world on 8/5/17! ❤️ Took 5+ years to get our little baby! Now pregnant again with baby #2, feeling over the moon! 👶🏼👶🏼
Has anyone else had severe anemia? I have crohns and no colon (internal pouch in place of colon) so I can't absorb nutrients very well. Did anyone have to get IV iron? Does anemia make you vomit and have severe fatigue? I'm just miserable!
