So what is Natural Killer Cells and why did Harley Street Fertility Clinic want me to have a test?

"If you are dealing with unexplained long-term infertility, or recurrent miscarriage (like me), one explanation offered by clinics could be that you have the presence of overactive Natural Killer Cells (NKC).  This is exactly why I had my bloods done at a clinic on Wednesday. They took 16 bottles of blood off of me, I was told my bloods were having a vacation and got flown to Chicago results back in 2 weeks. Hopefully this will help me understand why I have miscarried so many times. I just want some answers, this will be my final test. I have now had my thyroid tested which actually needing tweaking with meds, I’ve had the MTHFR gene tested which was positive. So now I’ve started taking folic acid in a more natural form with my prenatal multivitamins (better for all of us anyways) I’ve tested positive for an autoimmune condition called Antiphospholipid syndrome which is an autoimmune disorder. Signs and symptoms vary, but may include blood clots, miscarriage, rash, chronic headaches, dementia , and seizures . APS occurs when your body's immune system makes antibodies that attack phospholipids."
