After taking emergency contraceptive pills, some women may experience withdrawal bleeding, which is caused by withdrawal of the medication rather than actual menstruation. This withdrawal bleeding may last a few days or a week and then go away.

Secondly, emergency contraceptive pills may cause dietary changes in women. After taking emergency contraceptive pills, some women may experience nausea, vomiting, headache, dizziness and other symptoms, which may affect their eating and sleeping.

Third, emergency contraceptive pills may affect women’s health. After taking emergency contraceptive pills, some women may experience symptoms such as allergic reactions, spotting, and breast pain, which may affect their health.

Finally, long-term birth control pills may also cause some side effects. Long-term contraceptive pills may affect women's menstruation, weight, physical characteristics, etc., and may cause some side effects, such as withdrawal bleeding, headache, nausea, etc.

In summary, while emergency contraceptive pills and long-term contraceptive pills may cause some side effects, not all women will experience these side effects.
