The 14 days of IVF are equivalent to 31 or 33 days of a normal pregnancy. Normally, a normal pregnancy is based on counting from the first day of the last menstrual period, while IVF has to add 17 or 19 days forward. If the embryo transferred is a third day embryo, the transfer date will be pushed forward 17 days to equal the first day of the last menstrual period, then the 14 days of IVF will be equivalent to 31 days of normal pregnancy; if the embryo transferred is a fifth day blastocyst, the transfer date will need to be pushed forward 19 days to equal the first day of the last menstrual period, then the 14 days of IVF will be equivalent to 33 days of normal pregnancy. In addition, after determining the success of the pregnancy, you should pay attention to your own physical condition, pay attention to maintain a good state of mind, pay attention to a diversified and balanced nutritional diet, develop good habits of life and rest, avoid lifting heavy objects and overexertion, etc., and seek medical attention in time if you have any discomfort.
