Patient's question:
I had my period from November 1st to 4th. After taking emergency contraception on November 20th, my period did not come for 20 days. Am I pregnant? I had an abortion four months ago.Doctor's answer:
Your condition is caused by birth control pills. Emergency contraception contains a high level of estrogen. The dosage of one emergency pill is equivalent to 8 days of regular short-term oral birth control pills. Taking too much can lead to gastrointestinal discomfort, menstrual cycle irregularities, ovarian suppression, and other phenomena that disrupt the normal menstrual cycle, causing endocrine disorders. If taken for a long time, severe cases may result in amenorrhea. This can affect ovulation, thereby impacting fertility. Generally, no more than 3 pills should be taken in a year.
