I have a son aged 4 - conceived after much trying due to problems with me & hubby - really want another baby but no luck so far - am also concerned about the age gap even if I got pregnant now. Fed up with people saying stuff like - he's an only child is he? Makes me feel like I am depriving my son and I am on the scrap heap at 31 - nearly 32! Any advice please - feeling a little down.
