IVF is a procedure in which egg cells are extracted from mother’s womb and fertilised with a donor’s sperm. The complete process is conducted inside an incubator, and it takes around three days to complete the fertilisation process
After the sufficient development of the embryo, it is placed back in the womb of the mother. The mother is then advised to take a complete bed rest for twelve to fifteen days. After which a pregnancy test is conducted to confirm the success of the procedure.
It usually involves a serum pregnancy test for measuring the progesterone levels. This blood test confirms the pregnancy.

Some women tend to circumvent the required waiting time by buying lot of HPTs and testing themselves daily. They start a few days after embryo transfer, to check whether the HCG has cleared and the test is coming negative or not.
