I had a son during my 11 yr marriage which ended in divorce. I remarried in my 40s but no success in getting pregnant naturally, or with Clomid; then my periods became irregular and the menopause started. As IVF success rates for my age group are so low we decided against this, I just couldn't face the disappointment.
I feel so cheated especially as 1st husband has had 3 kids in 3 yrs with 2nd wife, yet no interest in another baby when we were together (I would have ended up doing everything for the kids, housework, shopping plus working full time whhile he was surgically joined to the computer. I felt like a single parent anyway. My only son decided to live with them and won't see me any more. I don't feel envious when I see mums with new babies, just a deep sadness.
