###Human: I consumed I-pill after unprotected sex. Will it delay my periods? ###Assistant: Hello. I have read your concern. It is a common side effect of I-pill to have prolonged menstruation and a delayed time for the next cycle. The emergency pill contains a high amount of hormone progesterone which prevents ovulation and at the same time hinders the usual period. If you want a regular cycle and not worry about getting pregnant, it is either you get birth control pills or have a copper IUD inserted. For now, you have to wait for your period. By the way, you will not get pregnant if it just touched the vagina.
