Hii,
This emergency pills can cause irregularity in the menstrual flow and frequency .
If you had unprotected sex, Do UPT and if it comes negative, again repeat it after 4 to 5 days and if both test show negative then don't need to be worried. You will get your period.
There could be more reasons for irregularity of menses like stress ,hormonal imbalances, sudden weight gain or loss,improper diet etc
Don't need to be worried .
