Pregnancy can occur during the perimenopausal period, but the probability is relatively low. Perimenopause is a period of time before and after menopause when the menstrual cycle is disrupted and hormone levels in the body are disturbed. During this period, although menstruation will be affected to a certain extent, the body may still ovulate, in which case pregnancy is still possible, but the probability is relatively low compared to the normal period. If there is no need to prepare for pregnancy during this period, it is still necessary to use effective contraception to avoid other problems. If perimenopause occurs, it is recommended to consult a doctor to determine the cause of the problem and to provide appropriate treatment or therapy.
