Currently going through a second miscarriage in 5 months. What is the next step? It seems we can fall pregnant but cannot get past 6 weeks. After scrolling for hours I am wondering about NK cells? Is it worth pursuing now or trying other tests first? Not sure why I am posting this but I feel lost. I have read success stories on here but the ones that stick out are those who have had many more miscarriages and still do not have their happy ending.
