Firstly are you sure you definately arent pregnant?? if answer is no then maybe have a chat with your doctor. Have you had irregular periods before the diet?? Cd can effect periods and it can take several months after finishing the diet for all to resume but having a chat with doctor will put your mind at rest,
Just check it over with your doc hun.
I had the opposite problem my period is now into its 8th week, i went to the doc and it wasnt anything to do with cd it was something else and im now getting sorted, so just ask you doc.xx
