Severe Pain from Periods,

All my life, well, ever since I started having periods, my pain would be quite severe , I Need to know if this is normal or not, many people including doctors say it is, but I just don't think so.

My symptoms have included these when it is at its worse:
cramps (obviously) sometimes so bad I can't walk
puking constantly
diarrhea constantly
no appietite
dizzyness and near fainting
sweating as though I was breaking a fever
looking pale in my face (as though all the blood was leaving from it)


Recently, a sharp pain has been happening on my right ovary on a regular basis, but especially on my period.. I had it checked out but the doctor said there was no cyst. (I don't believe him)

Now I'm on birth control, and all the symptoms above have diminished quite nicely, though when I take a week of sugar pills for my period to run its course, the right ovary begins hurting again, so sharp that I can barely walk.

So, what I guess I am asking is:
-Are those symptoms normal? (though I have found a solution, I just need to know)
- Is there a possibility my doctor was wrong, and I could have a cyst in my ovary? I had one in my breast once about a year ago.

**I swear, on my pelvic x-ray, I SAW a cyst or something on my right ovary!!**
