Question: what is 5 dpo in pregnancy?
Answer: What is happening in the womb at 5 DPO? At 5 DPO, if the sperm has reached and fertilized the egg, the cells within the newly formed zygote begin multiplying to create a lump of cells called a blastocyst. These cells continue to multiply as the blastocyst makes its way down the fallopian tubes and into the uterus.
