After the blastocyst is transferred into the uterine cavity, most patients have no symptoms at the time of successful implantation. Some patients may experience a range of symptoms, commonly including menopause, fatigue, breast tenderness, nausea, vomiting, small amounts of vaginal bleeding, and abdominal pain. 1. Menopause: This is the most obvious manifestation of successful embryo implantation. After successful implantation, the level of progesterone in the woman’s body increases, and the endometrium grows rapidly to provide nutrients for the development of the embryo, instead of shedding cyclically, so there will be the performance of menopause. 2. Fatigue: After the embryo is implanted, a large amount of progesterone and human chorionic gonadotropin will be secreted, which may make the patient tired and drowsy. 3. Breast swelling and pain: the estrogen and progesterone levels in the body will increase after the embryo implantation, which will promote breast development and prepare for breastfeeding in the later stage, and may result in breast enlargement, swelling and pain, sensitivity, and so on. 4. Nausea and vomiting: it is one of the most common symptoms after embryo implantation, but there are great individual differences between different pregnant women, some of them only have slight nausea, while some of them will have severe vomiting. 5. Small amount of vaginal bleeding: because the embryo will stimulate the endometrium when it is implanted in the uterus, it may cause a small amount of endometrium to fall off and a small amount of bleeding will occur, which is so small that it may only be seen on the underwear and will usually stop by itself. 6. Abdominal pain: Because the endometrium is stimulated when the embryo is implanted, or because of the hormonal changes in the body after implantation, there may be small abdominal pain or soreness and discomfort. After successful implantation of blastocysts, you should go to the hospital in time to confirm whether the implantation is successful. If you have any questions, it is recommended to consult a specialized doctor.
