The symptoms of pregnancy that appear on the eighth day after ovulation are mild abdominal pain, some people may have a small amount of vaginal bleeding, some people have no discomfort, and the symptoms may not be exactly the same for each person’s body type. On the eighth day after ovulation is the time for the fertilized egg to come to bed. Abdominal pain and bleeding will occur when the fertilized egg comes to bed, the vaginal bleeding will be minimal and will last 1-2 days. The pregnancy cannot be determined from the symptoms alone, but you need to go to the hospital to have a blood test for HCG in the blood to determine the pregnancy. The placenta will secrete human chorionic gonadotropin after the fertilized egg is laid, and this hormone will stimulate the body to produce nausea, vomiting and other early pregnancy reactions, and some may experience general weakness and other symptoms.
