How many weeks of pregnancy is the progesterone test

Progesterone is a very special substance during pregnancy and has major clinical significance for normal pregnancy. The progesterone content during pregnancy is also a key point of examination. When progesterone is insufficient, miscarriage may even occur. It is a natural progestin, also called progesterone in medical students. Even if you are not pregnant, when the level of progesterone secreted by the human body is too low, it will affect women's menstruation in some way.

How many weeks of pregnancy should I check for progesterone?

You can go for a check-up after your pregnancy is confirmed, usually within 35-50 days. Reference value: Because the units of conversion are different in various hospitals, if the reference value unit of the test report you received is ng/ml, you should convert it to nmol/L by X3.18. Progesterone has immune protection and can suppress immune responses. A study implanted certain tumor cells into the uterus of animals. Only in animals injected with progesterone were the cells not rejected and implanted into the uterine wall, indicating that progesterone can suppress the immune response. This also shows that when a woman is in a normal pregnancy, the increase in progesterone can prevent the embryo from being rejected by the mother and maintain the pregnancy. When there is a lack of progesterone, the embryo may be rejected by the mother and cause miscarriage. During ovulation, under the action of progesterone secreted by the corpus luteum, the endometrium transforms from the proliferative phase to the secretory phase, making the endometrium receptive to embryo implantation. Decidual cells are transformed from endometrial stromal cells and contain glycogen granules, which provide nutrition to the blastocyst. Progesterone can induce the decidualization of endometrial stroma and regulate the expression of various implantation-related factors in an autocrine or paracrine manner. Therefore, progesterone is necessary to maintain the decidual response. Progesterone testing can be done after pregnancy is confirmed. Expectant mothers also need to understand the normal values ​​at each stage so that problems can be discovered in time during the examination. Progesterone has many functions. After understanding them, expectant mothers may understand the importance of progesterone better. Symptoms of Low Progesterone

Progesterone, also known as progesterone, is a natural progestogen secreted by the corpus luteum of the ovary. It has a significant morphological effect on the endometrium stimulated by estrogen in the body and is necessary for maintaining human pregnancy. Low progesterone is often seen in luteal dysfunction. Threatened abortion, fetal growth retardation, etc., low progesterone can also affect irregular menstruation. So what are the symptoms of low progesterone? Abnormal menstrual period: A common symptom of low progesterone is that a woman's menstrual period becomes abnormally disordered, either early or late. Dysmenorrhea, heavy menstrual bleeding, and metrorrhagia are also symptoms of low progesterone. Habitual miscarriage: When a woman is pregnant, progesterone is necessary to maintain her pregnancy. If the progesterone level is low, the incidence of miscarriage will increase.
