After the test, why didn't my period come?

Patient's question:

I haven't had my period for one and a half months since the last time. I don't know why it hasn't come yet. The test results also showed that I'm not pregnant. Below, there's an odor, and the leukorrhea isn't much. It's white. First follow-up question: I'm 25 years old. Previously, my cycle was within 40 days. I used an early pregnancy test strip. Second follow-up question: What medication should I take to regulate my period? Thank you

Doctor's answer:

?Hello, a menstrual cycle that is one week early or delayed is considered normal. If a blood test for human chorionic gonadotropin (hCG) shows no pregnancy, it could be due to endocrine disorders. For endocrine disorders, medications such as progesterone or gynecological regulation tablets can be used to regulate the menstrual cycle. If menstruation does not occur for a long time in the future, it may be necessary to check the six hormones of sex hormone secretion.
