Pain like that is not normal. You may want to see a doctor about it. I have debilitating cramps and pain like that and I have endometriosis. Periods shouldn't be fun by any means, but if your pain is so bad that it disrupts your life, that is something to be concerned about..
I am so sorry about your pain I am going through a similar thing at the moment and ibuprofen dose not work for me at all but panadeine works wonders for me an if that doesn't work for you try ponstan my mum use to take it an her pain was so bad she use to vomit and then faint
