Doctor's answer:
Premature or delayed menstruation by one week is considered a normal phenomenon. Of course, if there has been sexual activity, blood and urine hCG tests, as well as ultrasound examinations, can be conducted after a one-week delay in menstruation to check for pregnancy. Delayed menstruation should also be considered due to factors such as poor rest, stress, gynecological inflammation, or endocrine disorders, all of which may lead to delayed menstruation. It is recommended to visit a hospital for tests of six sex hormones and ultrasound, avoid taking medication blindly, and undergo targeted treatment after identifying the cause.
