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 pills contain high levels of estrogen. The dosage of one emergency pill is equivalent to 8 days of regular short-term oral birth control pills. Excessive intake can lead to gastrointestinal discomfort, menstrual cycle irregularities, ovarian suppression, and other phenomena that disrupt normal menstruation, 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.
