If a woman is pregnant or in peri-menopause, it is normal for her not to have her period for 2 months, otherwise it is considered as irregular menstruation, which is not normal. The most typical sign that a woman is pregnant is the cessation of menstruation, so not having a period for 2 months after pregnancy is normal. If a woman enters the perimenopause, it will also lead to the absence of menstruation, which is due to the gradual decline of ovarian function, resulting in lower hormone levels in the body, and is also a normal physiological phenomenon. If you are not pregnant and not in peri-menopause, it is not normal for a woman not to have her period for 2 months. This phenomenon belongs to menstrual disorders, which may be caused by prolonged late-night work, excessive mental stress, endocrine disorders due to high stress, or uterine adhesions, polycystic ovary syndrome and other diseases. In conclusion, whether it is normal not to have a period for two months needs to be analyzed according to the specific situation. If there is a menstrual disorder, it is recommended to go to the hospital in time for a clear diagnosis and targeted treatment.
