Private Iron infusion [on]

Has anyone paid for a private iron infusion?

This is my second pregnancy and I started taking iron as soon as I found out because my last pregnancy my ferritin was 6 and I felt awful.

This time it’s low (20) and I don’t want to go through all that again so I would love an infusion. Will pay for it because it’s not worth me feeling tired all the time.

I’m almost 27 weeks, I see my OB in 2 weeks. How do I go about getting an infusion/ private one? Do I get a prescription? Can I just book at a clinic? I am in north GTA.
