Artificial insemination has two follicles, if both follicles are discharged, the formation of two fertilized eggs may both implant; if one follicle is discharged, the formation of one fertilized egg may also be implanted one; if there is no follicle is discharged, and the unfertilized egg is not formed, then it will not be implanted. After artificial insemination, if both follicles expel an egg and form a fertilized egg, then they may both implant; if one follicle is expelled and a fertilized egg is formed, it may also be the one that implanted; if no follicle is expelled and no fertilized egg is formed, it will not implant. If the fertilization is successful, there may be menopause, nausea and vomiting, breast tingling and other discomforts, which also represent successful conception. If your menstrual period is delayed after artificial insemination, it is recommended to go to the hospital to have blood drawn to test the concentration of human chorionic gonadotropin in your blood to determine whether you are pregnant. Usually, if there is any abnormality, it is recommended to consult a doctor in time and choose the appropriate way of treatment.
