Iron transfusions?

Anyone on here had iron transfusions while pregnant? I’m 30 weeks and just got told I have to get iron transfusions next week because I’m severely anemic. I was also told to stop working and rest which I’m worried about my husband hating me for because he works 2 jobs now, he says that I’m being ridiculous do that baby comes first but it just sucks I’m not longer going to be helping money wise.
