If the ovarian function of the expectant mother is not good, the body will not be able to secrete enough progesterone to maintain the development of the embryo after pregnancy, which may lead to the problem of fetal arrest. Therefore, for irregular menstruation, luteal dysfunction is not expectant mother, it is best to regulate the body, improve the endocrine disorders before pregnancy.

Fortunately, a large part of the abnormal uterine problems can be found in time through B-ultrasound and other gynecological examination, and treated and improved before pregnancy.
