Abdominal pain on the ninth day of ovulation does not necessarily mean that you are pregnant. This is because even if you are pregnant, the fertilized egg is only at the germ cell stage and has basically just entered the uterine cavity on the ninth day of ovulation, so it will not cause abdominal pain. If there is abdominal pain, it may be caused by gastrointestinal diseases, inflammation of the urinary system, stones, or inflammation of the pelvis. It is recommended to go to the hospital for relevant examination, only through the examination can we know the specific cause of abdominal pain. It is also recommended to combine the clinical history and the presence of urinary and fecal abnormalities to give a comprehensive analysis in order to know the cause of abdominal pain, and then give the appropriate treatment.
