I was born 11 days overdue, spontaneous vaginal delivery.
My mum went to an antenatal appointment at 10 days over in the afternoon, and the MW told mum she was in labour and 4cm dilated, although my mum wasn't feeling any pain whatsoever. Fast forward to 11pm that night, she had one pain, then 30 minutes later had another and from then on it was back to back contractions and I arrived at 2.20am. I weight 7lb 2oz's and my mum stayed in for 4 days after I was born, which was the norm then, but mainly because my dad was in a full leg cast having been in a motorcycle accident a few weeks before I was born!
She's always said that it was horrid and much preferred my sister longer but more conventional labour and birth to my rapid one that left her in shock for a little while.
Oddly, both, myself and H were born 11 days overdue, as was our daughter, so I'm not holding out much hope for this one which is already following in his parents and sister's footsteps!
