Covid antibody transfusion ?

Darian • Growing my rainbow 🌈 also if you’re here to start drama with me, let’s not.

I tested positive for Covid today (twice, cause work thought I was “lying” and made me come do one after I did one at homes but they’re dumb so anyways.) and I can’t go back to work til next Friday, contacted my OB and tomorrows appointment has been rescheduled for December 30th, plus little “post Covid” ultrasounds to check on little lady. She said something about an antibody transfusion?? Has anyone had this done while pregnant? What exactly is it? I’m terrified of needles so just want the process explained so I can prepare if I need one!
