The absence of any symptoms after ovulation does not mean that there is no pregnancy. The reason is that at this time, even if the sperm and egg have combined to form a fertilized egg, the fertilized egg is still in the germ cell stage and is very, very small. Moreover, it has not yet entered the uterine cavity and will not lead to changes in hormone levels in the body, so there will be no corresponding symptoms. Clinically, it is only after the fertilized egg has entered the uterine cavity that some symptoms appear gradually, such as increased secretions, anorexia, nausea, vomiting, and localized enlargement of the breasts, mild swelling and pain in the localized breasts, and coloring of the nipples and areolas. These symptoms will appear gradually after the fertilized egg has been laid for a period of time, not immediately after it has been laid, so the absence of any symptoms after ovulation does not mean that you are not pregnant.
