Pregnancy cannot be detected during ovulation, and the main indicator to detect pregnancy is the human chorionic gonadotropin test. During ovulation, the egg is picked up from the umbilical end of the fallopian tube and settled in the abdomen of the fallopian tube. If it encounters sperm, it forms a fertilized egg, which gradually moves from the fallopian tube into the uterus and forms a meconium after certain conditions of development and differentiation in the endometrium. The fertilized egg gradually moves from the fallopian tube into the uterus and after certain conditions of development and differentiation, it forms a meconium. It is only after the meconium has successfully colonized the endometrium that it gradually secretes human chorionic gonadotropin, so it takes some time to detect whether it is pregnant or not, so it is not possible to detect whether it is pregnant during ovulation.
