Patient's question:
Took birth control pills, still haven't had my period. It's been 18 days since I started taking them. My last period was on the 4th. Please ask the doctor if this is dangerous.Doctor's answer:
If everyone's constitution is different, so the delayed time also varies, generally it's around 10 to 2 days. There are many factors that affect menstruation, and it is closely related to diet, sleep, and mental state, so please regulate it in the future.Emergency contraception pills generally do not cause significant harm to the body, but side effects may lead to menstrual irregularities and delayed periods.
The mechanism of emergency contraception pills is primarily to inhibit ovulation or prevent implantation. Implantation refers to the attachment of the fertilized egg to the endometrium.
Emergency contraception pills should not be taken long-term. It is recommended to take them no more than two to three times a year. However, many young people are now using them as a form of contraception, taking them several times a month or even every month. This is not advisable.
I do not recommend taking emergency contraception pills continuously. Under normal circumstances, they are a backup measure, not a regular one.
Additionally, there are important precautions when taking these pills. Do not take them during suspected pregnancy. Some people take emergency contraception pills without understanding the risks. For example, if they think their period is coming and still have sexual activity, they take the pill—this is incorrect.
Second, those with cardiovascular diseases, migraines, or liver and kidney dysfunction should use caution. Breastfeeding women should also be cautious, as the medication can affect milk production and harm the baby. Women over 40 should avoid oral intake of these pills.
Moreover, long-term use of emergency contraception pills can lead to vaginal infections. For the sake of your health, it is better to choose safer and healthier contraception methods.
