After i took escapelle my periods came early and then the following month they didn't came why?

Normal experience: When you took this emergency contraception, it is a large dose of progesterone. It is common for women to experience a withdrawal bleed related to the medication that i believe you have mistaken for your period. Then it has the effect of delaying the onset of the next cycle. This is a common experience. Take a pregnancy test, use condoms and wait. If you do not get a period, talk to your doc!
