What happens four days past ovulation?
If you’re pregnant at 4 DPO, a sperm cell fertilized an egg that was released four days ago. This process usually happens inside your fallopian tubes. Once the egg cell and the sperm cell merge during fertilization, these two cells will transform into a zygote.
The zygote travels down the fallopian tube to reach the uterine cavity. At the same time, the zygote will start to divide into multiple cells. These cells are “totipotent,” which means that they can turn into any of the cells that make up the human body.
