My period changed from my normal 27-29 days and jumped to 35 days randomly. Eventually I realised it was due to stress (it was the end of my first Uni year...lots of exams and assignments!). Went back to normal eventually   -- Posted by girlbythewhirlpool at 4:00 pm on Dec. 18, 2008 there isn't a way, if you've drank a lot of alcohol recently it can postpone it, not something to worry about though as long as it comes eventually. -- Posted by FiercexMelon at 5:39 pm on Dec. 18, 2008 People say drinking parsley tea or taking black cohosh can induce it. I've tried both with no results.
