I've been TTC for about 8 months..I'll be 34 next month (God willing) and my son will be 13 in October (once again God willing). I'm starting to think I'm too old for starting all over again. I'm starting to think I should just be grateful I've been blessed with one healthy child. I'm starting to feel bad because I'm yearning for something I've already had and some women haven't had the chance to experience motherhood at all. Anyone else feel this way? Am I alone?
