Anyone else prescribed Hydroxychloroquine for NK cells

Hi ladies, I'm currently under a misscarriage clinic (Mr Shehata) and was first given prednisolone and cyclogest, only been on it for 3 months- after having a miscarriage last year. Treatments have now resumed again in the clinic and they have now prescribed hydroxychloroquine 400mg & cyclogest. Has anyone else know of hydroxychloroquine being used for elevated nk cells resulting in a BFP

Just really trying hard for #2. It's been 10 year long journey so far.

Any replies will be much appreciated. Thanks ladies.
