The week of conception is usually the time between the first day of the last menstrual period and the current pregnancy, and there is no difference in the calculation of the week of conception whether conception occurs during the pre-ovulatory or post-ovulatory period.
Fertilization, where the sperm and egg meet and combine to form a fertilized egg. In the pre-ovulatory period, i.e., 1~2 days before the egg is discharged, if you have intercourse at this time, the sperm survives in the woman’s body for 2~3 days, and only after the egg is discharged, it combines with the egg for fertilization. In the late ovulation conception, that is, after the egg is discharged 1~2 days after intercourse, the sperm only into the woman’s body and the egg fertilization.
Because in these two time periods, both pre-ovulation conception and post-ovulation conception need to wait for the woman’s eggs to be discharged, the egg exists before fertilization, and the calculation of gestational weeks itself is not concerned about whether it is in the pre-ovulation or post-ovulation coitus, so the calculation of gestational weeks in the pre-ovulation conception and post-ovulation conception pregnancy week is not very different.
If the pregnant woman is not clear about the calculation of her pregnancy week, it is recommended to go to the hospital in time, under the guidance of the doctor to do the calculation. After confirming the pregnancy, you should follow the doctor’s instructions to take the delivery test on time, and if you are not feeling well, you should go to the hospital in time and follow the doctor’s instructions to deal with the treatment.
