My mum's last pregnancy resulted in twin boys despite being told after every ultrasound that she was having 1 GIRL! *L* The twin's hearbeat was in sync and one always completely shaded the other in the U/S.

Just in case any of you are wondering whether it is possible to go full term and have a completely natural birth...it IS possible. *L* Mum obviously didn't know that she was expecting twins but she went to 40wks with them and delivered them from start to finish in 3 hours of labour (twins were born 3 minutes apart) with only one small stitch required.
