The top 10 signs of successful frozen embryo transfer is an unscientific statement. Early pregnancy reaction, breast swelling, frequent urination and other symptoms can occur after successful transfer. 1. Early pregnancy reaction: Frozen embryo transfer is a method of embryo transfer and assisted reproductive technology, which needs to be operated by professional doctors. After the frozen embryo transfer is successfully implanted, due to the elevated hormone level in the body, early pregnancy reactions such as nausea, vomiting, fatigue, anorexia and drowsiness will occur. 2. Breast swelling and pain: also due to the increase of hormone level in the body, the volume of the breast gradually increases, conscious breast swelling and pain, nipple and areola will also appear hyperpigmentation. 3. Frequent urination: it is caused by the increasing uterus pressing on the bladder in the pelvis, which will disappear naturally with the increase of pregnancy weeks when the uterus exceeds the pelvis. About 2 weeks after the frozen embryo transfer, you can follow the doctor’s instructions for blood or urine HCG (human chorionic gonadotropin) level measurement to determine whether you are pregnant or not.
