Patient's question:
Doctor, hello. I have had an abortion before. My last menstrual period was on the 20th of last month. Recently, I have often felt very tired, with a full bladder, and have experienced vomiting. It feels like I might be pregnant again. Before this, I had two sexual relationships, but I took birth control pills afterward. My menstrual period should be around the 16th of this month. Should I wait a bit longer or should I go to the hospital for a check-up?Doctor's answer:
Emergency contraception pills are generally used when no contraceptive measures are taken or when contraception fails. They can be effective if taken within 72 hours. Emergency contraception pills only provide contraception for sexual activity before taking the pill and have no effect on sexual activity after taking it. However, taking multiple doses of emergency contraception pills in a short period of time can lead to menstrual disorders, ectopic pregnancy, and contraceptive failure.
