With DD1 i didn't think it was transition as id only been in labour for 5 hours (little did i know id be pushing for another 2 hours to get her out!) but i threw up and cried that i couldn't do it anymore and wanted to go home to bed with DD2 i knew it was transition because the exact same thing happened, i threw up and again cried that i couldn't do this anymore and wanted to go home to bed - i never got the double contractions, they were just really long and painful then nothing for about 2 mins then next thing i knew that immense bowl pressure was there and i was pushing!
