Whether or not a woman can get pregnant with a 3mm endometrium needs to be judged in conjunction with her menstrual cycle, and the thickness of the endometrium varies from one menstrual period to the next, so you can’t make any generalizations. The endometrium is divided into three phases according to the menstrual cycle: proliferative phase, secretory phase, and menstrual phase. proliferative phase is the 5-14 days of the menstrual cycle, which corresponds to the follicular phase in the ovarian cycle, and the thickness of the endometrium is about 3-5mm. secretory phase is the 15-28 days of the menstrual cycle, which corresponds to the luteal phase in the ovarian cycle, and the thickness of the endometrium is up to 10mm at the end of secretory phase, that is, the 24-28 days of the menstrual cycle. Just after a woman’s menstruation, because she has not ovulated, the endometrium will be thinner, only 3mm, and this is usually normal. If the endometrium is only 3mm thick after ovulation, it is an abnormal phenomenon, which may be related to the lack of estrogen, endocrine disorders or scraping damage to the endometrium, which is not conducive to pregnancy. If a woman’s endometrium is only 3mm thick after ovulation, it is recommended to actively go to the relevant departments of regular hospitals for examination, to find out the specific causes, and actively follow the doctor’s advice to adopt the appropriate solutions; usually to develop a regular routine, to ensure adequate sleep, do not stay up late, but also to strengthen the diet and nutrition, which is conducive to good health.
