Can stopping the birth control pill affect your period?
When you stop taking the birth control, your period may change
in a few ways. First, it will probably get a bit heavier and
crampier again, reverting to the pattern it had before you started
the pill. (Since the pill makes most women's periods lighter and
less crampy, stopping it removes this benefit.) Second, your period
may not have the same timing it had when you were on the pill. When
you stop, your next period will come in 4-6 weeks.
