The menstrual period that arrived on the 5th is bleeding again on the 18th. What is the reason?

Patient's question:

No

Doctor's answer:

During sexual intercourse, there is bleeding. If there is internal ejaculation during coitus, pregnancy can be considered first. It is recommended to use an early pregnancy test to check if you are pregnant. If you are not pregnant, then bleeding during intercourse is commonly caused by conditions such as cervicitis or cervical erosion. It is advised to visit a hospital for a gynecological examination.
