Menstruation did not come how to return a responsibility

If a woman with a history of sexual life has delayed menstruation for seven days and has not considered the possibility of pregnancy, she can use early pregnancy test strips to test whether she is pregnant. It may be ruled out that the pregnancy may be caused by menstrual disorders caused by endocrine disorders. Blood tests can be taken to check sex hormones. Etiology, women's menstrual cycle can be affected by many aspects such as environment, diet, mood, and drugs.
