Question
Hello doctor.
The doctor asked me if I can take birth control pills every day when I don't have a period? Will such use affect the effectiveness of the drug? This is my first time using the drug. I hope you can give me some advice, thank you.

Hello!
The contraceptive mechanism of the daily oral contraceptive pill is to prevent ovulation. The drug works to prevent ovulation after taking about 7 days. Therefore, if you take the pill when you have not had your period, it will reduce or not be effective at preventing pregnancy.
To take the pill to achieve high contraceptive effectiveness, you should follow the manufacturer's instructions for use.
