Hopefullyanotherbaby I'm so sorry you're worried about the cramping, I really hope it all turns out ok for you. Dr Allan Beer's book is very strong on the ridiculousness of doctors calling recurrent miscarriages "bad luck"... He says that is simply not true & not a scientific diagnosis, doctors don't tell cancer or diabetes etc patients it was bad luck, why then is infertility? How & why is that acceptable? I really urge you to consult with Dr Matthias in conjunction with Genea. Dr Alison Gee believes in NK cells & will work with Dr M's protocol. If YOU believe in NK then go to a doctor who does too otherwise you'll be in for more grief. I hope you don't have to & this pregnancy sticks!!!
