As the term emergency contraceptive itself means that it should be used only in case of an emergency. It should not be used as a regular contraceptive. Second, as understood, it is a hormonal pill. So all hormonal pills do have certain types of side effects, so one should restrict using them as far as possible and use them only in case of certain conditions. There are problems such as delayed periods, irregular periods, irregular bleeding and weight gain that can happen in a long term basis by taking overconsumption of emergency contraceptive pills.
