Patient's question:
After the menstrual period, one week later, I had sex and took emergency contraception. A week later, my period came again. Then, it has been more than fifty days since then, and my period still hasn't come. A pregnancy test showed that I wasn't pregnant. What could be the reason for this!Doctor's answer:
After taking emergency contraception, withdrawal bleeding generally occurs in two cases: one is a small amount of bleeding, lasting for 2-3 days, then the next menstrual period can be referenced based on the original menstrual date; the other is bleeding volume and duration similar to regular menstruation, which is also the menstrual period, indicating that the previous sexual activity was successfully. The next menstrual period can be referenced based on the date of this bleeding.
