I want to ask next, menstruation sees what reason is postponing

Delayed menstruation may be related to factors such as pregnancy, endocrine disorders, mental stress, and taking drugs containing progesterone. Intrauterine adhesions caused by intrauterine surgery can also lead to delayed menstruation. Traditional Chinese medicine believes that delayed menstruation is related to liver depression and qi stagnation, kidney deficiency, and qi and blood deficiency.
