Patient's question:
I would like to ask: I had sex with my girlfriend seven days before her period started, and after the act, I took the medication as instructed within 72 hours. However, now three days after her period should have arrived, she hasn't had her period yet. Additionally, she has been urinating more frequently, and there seems to be a small amount of something like menstrual blood. Please tell me what could be happening. I am very worried. Please give me an answer quickly. Thank you.Doctor's answer:
Emergency contraception pills work by disrupting the hormonal balance in the body to achieve the purpose of post-coital contraception. Therefore, taking emergency contraception pills can easily cause menstrual cycle disorders, which is also a common consequence of emergency contraception pills. Emergency contraception pills are not a guaranteed method: the effectiveness of emergency contraception pills is only about 85%, lower than that of short-term oral contraceptives (99%) and condoms (95%). Moreover, the more frequently they are used in a short period, the lower the effectiveness. Therefore, it is important to carefully choose a method of contraception, such as the safe period or condoms, and wish you good health.
