The IVF process usually takes 2-3 months, but the exact time varies from person to person and cannot be generalized. Before performing IVF, the couple needs to complete a series of tests to clarify whether there are any organic pathologies and whether all functional indicators are normal. If there are no abnormalities, the couple can officially enter the IVF cycle. Depending on the patient’s specific situation, the doctor will develop an individualized ovulation promotion program. After 2-3 days, if the endometrial thickness and morphology are suitable for transfer, the embryos can be transferred and the pregnancy can be determined by blood HCG check after 14 days. If there are no special reasons, it takes about 2 months for a normal couple to complete all the above processes, and if there are other special reasons, it may be extended to 3 months or even longer. During the IVF preparation period, it is important to maintain a good mood, avoid excessive stress and anxiety, eat a nutritious and balanced diet, take folic acid supplements and keep warm to avoid getting cold.
