Have you talked to your parents about this? I would see a women's health doctor such as a gyn. or at least a general practitioner that has those services. They can check things that may cause some of the abdominal cramping feeling as well as run some other tests to rule out problems with your reproductive system. It could be as simple as ovulation pains or ovarian cycsts which are commen in teens. It's worth having it checked.
Now the lightheadedness and blacking out... I had when I was a teen and young adult. Mine was related to lowish blood presure and I was advised by my doctor to get up slower. But that should be checked out too when you see your doctor.
Hi
Most head injuries are closed injuries, and may manifest no visible injury. A head injury may not cause immediate symptoms. Dizziness, headache and vomiting for no apparent reason are a common result of mild traumatic brain injury (MTBI). They may manifest as late symptoms of the injury.
Other late symptoms may include, convulsions, vacant or dazed expression, drowsiness, general weakness in the arms or legs, loss of memory of the injury, clear fluid or blood coming from the nose or ear, difficulty speaking, numbness, paralysis, sleeping more than usual, difficult to wake up, loss of coordination and unequal pupil size.
You should consult your doctor to treat the underlying cause. Various tests including blood tests, CT scan, MRI are usually necessary to establish a diagnosis. Do write in after your doctor’s opinion and in case you need any other information.
Take care
