Advice needed please!!!!

Me and my husband have been trying to conceive now for 6 and a half years! We've had pregnancies but the have ended in miscarriages! We've been on fertility drugs! Our problem is I have PCOS and a chromosome translacation of 6 and 9 which makes it hard to conceive and if we do get pregnant it could end in a miscarriage or the baby developing disabilities! I'm at a loose end, my husband says if we don't have a baby he's fine with it but I know he really wants one so do I leave him so he can have a family he deserves and wants xx
