This might be because I'm in my mid 30s now and bio clock is ticking. I have one child age 6. Been single since he was a tiny baby. Feeling a huge pull to have another child. If I didn't have my son already I would consider sperm donation, but just can't risk one child having a father in their life and another not. I think that's probably it for me. One lovely child and done. Feeling very tearful about it at late. Does it pass? I can't be alone in feeling this way?
