High NK cells

Hi all, I have recently been diagnosed with high NK cells after having a miscarriage back in February and have been put on a treatment plan. I’m fine for this (once adjusting to the news, and being overwhelmed by the amount of drugs I have been given) but I’m concerned that since my miscarriage in February, I have been actively trying to get pregnant but haven’t managed to actually fall pregnant. From reading online the NK Cells seems to cause miscarriages more then infertility. Has anyone been unable to get pregnant because of NK cells? Did the treatment plan help you conceive? Thanks
