Symptoms after embryo transfer are typically similar to regular pregnancy symptoms, which include possible implantation bleeding and increased hormone levels. The hormone levels begin to increase and secrete into the bloodstream at around 6 days after the embryo transfer, and this hormone can be detected on a home pregnancy test to confirm pregnancy at around 9 days after embryo transfer.
Implantation occurs typically around 3 or 4 days after the embryo transfer. During implantation, the embryo attaches itself to the uterine wall, which can cause cramping and a small amount of bleeding. The pregnancy hormone, human chorionic gonadotropin, is released in higher amounts once the pregnancy begins. The increase of the hCG hormone in the body can cause numerous symptoms. Sore and tender breasts are a common early sign of pregnancy. Increased blood flow throughout the body, especially in the kidneys, can lead to more frequent urination.
Increases in other hormones, such as progesterone, can cause fatigue and lack of energy. While morning sickness is often seen at various points throughout the pregnancy, it can begin as early as 3 weeks after the embryo transfer. Some women notice that they begin to be more sensitive to smells once the hormone levels in their bodies increase. It is important to note that each woman's pregnancy is different, and not all of these symptoms become evident.
