A woman who has not had her period for three months and has no abnormalities in her hormone profile may be suffering from pregnancy, menstrual disorders or menopause. 1. Pregnancy: Women of childbearing age who have not had a period for three months and have had unprotected sex need to consider whether they are pregnant. Even if there is no abnormality in the six hormone tests, the possibility of pregnancy cannot be ruled out completely, and ultrasound as well as HCG tests are also needed. 2. Menstrual disorders: If a woman’s menstrual period has not come for three months and pregnancy is ruled out, it may be caused by menstrual disorders. If the patient has been overstressed, stressed, or has irregular diet, it may cause endocrine disruption and lead to menstrual disorders. 3. Menopause: If a woman has not had a period for three months and her hormones are normal, she may be in the perimenopausal period, experiencing menopause or irregular menstruation. Women who have not had a period for three months and have a normal hormone six, should go to the hospital in time for further examination to clarify the cause and then give targeted treatment.
