After taking the emergency contraceptive pill, there is usually no special reaction. If the body is sensitive, there may be nausea, vomiting, dizziness, diarrhea or general weakness, and some women may experience a small amount of vaginal bleeding. These symptoms can be gradually relieved as the drug is gradually metabolized. If vaginal bleeding occurs within 10 days of taking the pill, and the amount of bleeding is similar to the amount of menstruation, it can be confirmed that the contraceptive is successful. The emergency contraceptive pill can only be used as a remedy for contraceptive failure after sexual intercourse, but not as a regular contraceptive method. Some drugs are strict about food and time, and you cannot eat within two hours before and after taking the pill.
