At the age of 43, if your period is not coming, it is likely that you are already in menopause. The age of menopause varies depending on individual differences, for example, some people do not have menopause until they are 55 years old, while others have menopause just after the age of 40, which is clinically normal. The age of menopause in women is influenced by family genetics and the first menstruation, because the time of menstruation in a woman’s life is about 30 years, and the number of ovulation is about 400, so if the age of menstruation is early, the age of menopause will also be earlier. In addition, if you work under a lot of stress, stay up late, smoke and drink too much, it will also lead to early menopause.
