im 38+3 today and i had a bloody show yesterday morning. i went to the doc and she said my outer cervix is open and inner cervix is still closed (didnt know there was 2 lol until this point) anyway, i read after bloody show u get into labour 24-48 hrs later but the doc said i could be another week so im now so confused.. any thoughts??? how can i have a bloody show and not yet dilated? did this happen to any of u and if yes when did u get into labour after bloody show?
