Period Pains and Nausea

Emma
So as my period is about to start, I'm already feeling the slight burn of the cramps beginning. It's that fear that comes with it as I'm begging for it to be a simple period. 
But, unfortunately, it's never been that simple. I have haemophilia, a blood disorder that effects blood clotting and apparently makes my period worse than average. I take mephanemic acid for the pain and cyclocapron for the bleeding. 
When my period starts, I'm basically paralysed for a week. But now, on top of the burning pain, there is this unbearable nausea that has only recently begun. I will not be able to eat anything or it will end up coming back up, I can't sleep because of the wooziness. I can't think!
Please tell me this is normal and that it will go away some day? Help!
