I’m 32 years old – so why am I and all my friends so worried about fertility?

We were walking along the seafront, the tide way out in the distance and unseasonably warm sunshine beating down. Everyone in the group was pregnant, except me. They’d discussed due dates and names, weird cravings and 12-week scans, then came the confession: if I’d known it would happen that quickly, I probably would have waited a little longer and worried a little less.
