Progesterone is a hormone secreted by the corpus luteum in a woman’s ovaries. Insufficient progesterone after pregnancy can lead to failure of fertilized egg implantation or an unstable state after implantation, increasing the possibility of pre-eclampsia miscarriage in early pregnancy. Therefore, maintaining a certain state of progesterone level is an important factor in maintaining the maternal pregnancy state. When progesterone is low, you can eat more foods rich in phytoestrogens, such as soybeans, black beans and their soy products, such as soy milk, soy milk, tofu, soy skin, etc. In addition, millet and royal jelly can also be consumed, which have a certain auxiliary effect on increasing progesterone. If progesterone is too low in the body, diet alone is not enough, you can follow the doctor’s advice according to the test results and take progesterone capsules or intramuscular progesterone injections to supplement it. If the progesterone level increases and the HCG level rises, it proves that the fetal preservation is effective. In daily life, you should also pay attention to strengthen nutrition, avoid eating cold and stimulating foods such as iced water, raw garlic and pepper, get enough sleep to avoid staying up late, do not engage in strenuous activities, and have regular pregnancy checkups.
