It takes about 48-72 hours after intercourse for a couple to conceive. Since pregnancy is a complicated process, quality sperm has to reach the fallopian tubes through the vagina and combine with quality egg cells to form a fertilized egg, which will be transported to the uterine cavity in a smooth state, and the fertilized egg will face implantation when the uterus is in the best condition, and only after completing implantation is the pregnancy really successful. In this process, if the sperm is not in good condition or the egg quality is poor, it will directly affect the formation of the fertilized egg. After intercourse, women should not only pay attention to rest, but also keep enough sleep, do not exercise strenuously, and replenish the nutrition needed in the body in time to provide good conditions for the combination of sperm and egg.
