Patient's question:
After the last sexual activity, I took emergency contraception. However, it has been half a month since my last period, and I haven't had it yet. The pregnancy test strips I bought from the pharmacy also didn't show pregnancy.Doctor's answer:
Emergency contraception pills, due to their effects of inhibiting and delaying menopause and inhibiting the endometrium, can delay the next menstrual period. They may also cause a temporary decrease in hormone levels in the blood due to temporary medication. Emergency contraception pills contain hormones, which can cause the menstrual period to come earlier or later, and may even lead to a recurrence of withdrawal bleeding. Therefore, emergency contraception pills can disrupt the menstrual cycle.If menstrual cycle disorders persist for less than 3 months, it is recommended to undergo an endocrine hormone test, as emergency contraception pills can cause abnormal changes in the body's endocrine hormones. Based on the test results, periodic regulation can be implemented to help restore normal menstruation. Therefore, taking emergency contraception pills should not exceed three times within a year.
