When the fertilized egg has just been laid, there may be a small amount of vaginal bleeding, abdominal pain, and prolonged duration of the high temperature phase, but most women do not have any reaction. When the fertilized egg has just implanted, it may cause some damage to the uterus, which may lead to a small amount of vaginal bleeding and abdominal pain, but not all women will experience this symptom.
