How to calculate the expected delivery date of test tube baby

summary

My cousin and my sister-in-law have been married for several years, but they have no children. Only after going to the examination did they know that they were infertile. The doctor asked them to be test tube babies. After hard work, they are finally pregnant. Now, I'd like to talk about how to calculate the expected delivery date of IVF.

How to calculate the expected delivery date of test tube baby

First of all: the algorithm of test tube baby's due date is the same as that of natural born children, which is calculated from the time of last menstruation. But the algorithm of the last menstruation of test tube baby is different. In clinic, the transplant date is pushed forward 17 days as the time of the last menstruation, that is, the transplant date minus 17 days is the time of the last menstruation, and then the date of the last menstruation minus 3 or plus 9, and the date plus 7 is the expected delivery time.

Secondly: the expected delivery date of test tube baby is also calculated according to the last menstruation, which is the month of the last menstruation plus nine or minus three, and the number of days plus seven. The expected delivery date is calculated, because the test tube baby is also matched according to the thickness of endometrium and the normal time of self fertilization.

Finally: test tube baby is calculated as normal pregnancy, because the development process of pregnant eggs is the same. The expected date of delivery is calculated according to the last menstruation. The date of your last menstruation is pushed forward two weeks. The month of your last menstruation plus nine or minus three, and the date plus seven is the expected date of delivery. You take your eggs on March 23, the last menstruation is about March 9, and the expected date of delivery should be December 16, Due date is just about the time of birth, not all fetuses will be born on the due date. Generally, it is normal for fetuses to be born two weeks before and after the due date
