Not too old: I am sorry to hear about your miscarriages, Was the 46 XY the miscarriage Genetic testing? you look fertile though, and your husband, you probably need counseling by a high risk pregnancy specialist given your history. Preimplantatiion Genetic Diagnosis may be an option to avoid implanting an imperfect fetus (the reason for most early miscarriages) but the experts know better. good luck
