Patient's question:
I have been taking birth control pills (short-term 18-alpha) for a long time. Recently, for convenience, I switched to long-term birth control pills for several months. But this time, my period hasn't come (the last period was on October 12). I went to the hospital for an early pregnancy test, and it didn't show pregnancy.I would like to ask for your help to explain this!
Doctor's answer:
Generally, emergency contraception pills contain a large amount of hormones, which can cause side effects such as menstrual disorders. This also includes delayed menstruation, so your current situation is normal. You should wait for a while to see if it improves. Usually, it can return to normal within 2-3 months after stopping the medication.Emergency contraception pills contain high levels of estrogen. The dosage for one emergency pill is equivalent to the amount of a regular short-term oral contraceptive taken over 8 days. Taking too much can lead to gastrointestinal discomfort, menstrual cycle disorders, ovarian suppression, and other phenomena that disrupt normal menstruation and cause endocrine disorders. If taken for a long time, severe cases may result in amenorrhea (absence of menstruation). This can affect ovulation, thereby impacting fertility. Generally, no more than 3 pills should be taken in a year.
