It is said that pregnancy is a long process, from silent to violent reaction, all mothers go through the same process. Regarding early pregnancy reactions, have you experienced nausea and vomiting in the first 10 days of pregnancy? What is the reason for this? You feel nauseous and want to vomit. Some people begin to suffer from morning sickness in the first few weeks after pregnancy. You may feel nauseous or vomiting, and although morning sickness is also called "morning sickness," nausea and vomiting are not limited to the morning. You may feel nauseous all day and all night long. Breasts become softer. If your breasts feel tender, soft, and swollen, you may be pregnant. This type of symptom may appear in the first few days after pregnancy. After your body absorbs a large amount of testosterone, this pain will disappear and your breasts will no longer feel uncomfortable. Feeling tired. A lot of metabolism of luteinizing hormone (a male hormone) can make you feel exhausted. Almost all pregnant women suffer from this symptom, and you can observe other symptoms to confirm your suspicions. Frequent trips to the toilet. After the sperm and egg combine and implant in the endometrium, they begin to secrete human gonadotropin (hCG). This will stimulate you to urinate more often, so you may pee more often than before. Bleeding or muscle spasms. Eight days after ovulation and implantation, you may develop light pink or dark brown stains, and cramps may accompany these conditions. In fact, during the menstrual period, there may be some spotting and bleeding, but this is not a true menstrual period. It is the result of the fusion of sperm and egg and the implantation of the embryo in the uterine wall. What are the reasons for unsuccessful embryo implantation? The whole process of embryo implantation is silent, and there is no major change in the human body. If the embryo fails to implant, there is no pregnancy. If there is no pregnancy, the menstrual cycle will continue normally and the menstruation will occur on time. Therefore, if the menstrual period continues to be normal, it means that the last sperm and egg combination was unsuccessful. The reasons for unsuccessful embryo implantation are as follows: The sperm-egg combination itself has defects: because the sperm-egg combination itself has defects. Uterine factors: Failure of embryo implantation may be due to uterine hypoplasia, cervical fibroids, uterine intrauterine polyps, intrauterine adhesions, uterine wall tuberculosis, etc. Immune factors: Scientific research on immune factors in recent years has found that there are two immune conditions that affect pregnancy. Immunity: Sperm, seminal plasma or sperm-egg combination are antigenic substances. After being absorbed by the vaginal and uterine epithelial cells, antibodies are produced through immune response, which prevents sperm and egg cells from fusing or sperm-egg combination from implanting. Autoimmunity: Infertile women have autoantibodies in the zona pellucida of their blood cells, which react with the zona pellucida to prevent the male sperm from penetrating the egg cell, thus preventing fertilization. Ovarian corpus luteum insufficiency: If a woman's progesterone metabolism is insufficient, abnormalities will be found in her uterine wall, which will affect embryo implantation. |
