You need to check to determine whether you are short of progesterone. Generally, the endometrium will be detected within 0/2 hours of menstrual cramp/kloc-,or:
1. Diagnostic curettage: This kind of luteal function test is to observe the size and shape of the official cavity, whether the uterine wall is smooth, soft and hard, and the characteristics of by-products, and to know whether there is ovulation or whether the luteal function is sound. In anovulatory patients, the endometrium is proliferative and there is no change in secretion period; In patients with luteal insufficiency, the endometrium still stays in the early secretory stage before menstruation; For patients with luteal atrophy, oral administration was mixed on the fifth day before menstruation. Pay attention to the timing of curettage. 2. Determination of basal body temperature: The basal body temperature of normal women rises after ovulation, and the luteal phase temperature is 0.3-0.5℃ higher than that of proliferative phase, and the basal body temperature of anovulatory women is haplotype; Those with ovulation and luteal insufficiency are biphasic in basal body temperature, but the increase is slow, and the luteal phase is short, generally about 10d; In patients with corpus luteum atrophy, the basal body temperature is atypical biphasic, and the temperature drop is delayed or gradually decreased. 3.B-mode ultrasound monitoring ovulation: this method of luteal function examination is non-invasive to patients and harmless to germ cells, and can continuously and dynamically observe follicular development. Vaginal ultrasound can detect 5mm follicles with appropriate diameter. A group of small follicles can be detected at 6g on the 5th-7th day of natural ovulation cycle, and develop into dominant follicles with a diameter of lomm on the 8th-12nd day. After that, the dominant follicles increase at a rate of 2-3mm per day and gradually develop into mature follicles. It is recommended to see a doctor and have a regular check-up. I wish you health!
