I had a blood transfusion about 3 weeks ago due to a miscarriage.when is it safe for me to get back to exercising? thank you.

Anemic: Sorry to hear about miscarriage. As for blood transfusion, that means you were anemic and needed blood. Your normal hemoglobin is probably about 12 to 14. You were likely down to a 7 or 8. Assuming you are on iron now. I would ask MD what count is now, would be OK to exercise when around a 10.5 typically without getting short of breath. Ask your doctor about your situation.
