Patient's question:
On February 4th, I had sex with my boyfriend. On the 5th at noon, I took a birth control pill. By the 13th of the same month, my period came, which was four days earlier than in January. But my period hasn't come yet in March. I want to ask, is this due to a failure of the birth control pill?Doctor's answer:
Premature or delayed menstruation by one week is a normal phenomenon. Of course, if there has been sexual activity, you can check blood and urine hCG, ultrasound, and other tests one week after the menstrual period is delayed to see if you are pregnant. Menstrual delay should also be considered due to factors such as poor rest, mental stress, gynecological inflammation, or endocrine disorders, all of which can lead to delayed menstruation. It is recommended to go to the hospital for tests of six sex hormones and ultrasound. Do not take medication blindly; identify the cause and receive targeted treatment.
