Estrogen can be discontinued 8 to 10 weeks after pregnancy if there are no abnormalities in the fetus or the pregnant woman. Estrogen plays a greater role in women’s pregnancy. Estrogen promotes peristalsis of the fallopian tubes to facilitate the combination of sperm and egg into a fertilized egg, and is related to the maintenance of the luteal phase, and also stimulates the development of mammary glands to prepare for lactation. If the level of estrogen is low, it is not conducive to the embryo’s implantation, and it is easy to cause embryonic sterilizations and miscarriages. At 8 to 10 weeks after pregnancy, the embryo has already been laid, and at this time, the placenta can basically maintain its content, and the estrogen level is more stable, so there is no need to supplement additional estrogen. After pregnancy, you should pay attention to a balanced diet, regular work and rest, keep a calm mind, go to the hospital regularly for maternity checkups to ensure the health of the fetus and the mother, and avoid unauthorized use of medication.
