Patient's question:
Detailed medical condition and consultation purpose: Took short-term oral contraceptives for over two years and stopped last month. The last menstrual period was on October 31st. Since stopping the medication, menstruation has not occurred. Condoms have been used for contraception during this period. The purpose of the consultation is to understand the effects of stopping oral contraceptives on the menstrual cycle.Duration and persistence of the current illness: Menstruation has been delayed by one week compared to before.
Medical history: Two induced abortions, and has been taking oral contraceptives continuously for over two years.
Doctor's answer:
According to the contraceptive principle of emergency contraception, the biggest side effect of taking emergency contraception orally is causing a delay in menstruation, and a delay of two weeks is generally normal. The contraceptive principle of emergency contraception is to delay ovulation, block fertilization, or change the uterine lining environment to disrupt the implantation of the fertilized egg. It is effective to take it within 72 hours after sexual intercourse.
