Is it normal to have irregular periods after stopping birth control. I used the birth control patch and I'm supposed to wear it for 3 weeks(changing every Sunday) and take it off the 4th week.. I a got a period Feb 18th -23rd which was normal because that is whats supposed to occur during the 4th week but Feb 24th I took it off (mid week, week one) and 5 days later, March 1st - 5th I got a period (withdrawal bleeding) . Question is can my period be irregular still?
