Doctor's answer:
Hello, it's the safe period, so the possibility of pregnancy is not high. However, the safe period is not 100% safe and there is still a possibility of an unexpected pregnancy.

Once it is confirmed that you are not pregnant, you should also check for any gynecological inflammation.

If you are not pregnant but your period still hasn't arrived, it is recommended to visit a gynecological department in the hospital for examination to identify the cause before treatment.
