Booty cramps.....

Alayjah
Okay so every time I'm on my period I get these unbelievably sharp and painful cramps......but in my bootyhole tho. It's like I need to poop really bad but PAINFUL as fuck and sometimes short, maybe a few minutes, and other times, like an hour long. It hurts like in my ass and in my lower stomach and sometimes in my back that I can't walk and applying pressure like breathing to hard or laughing (I laugh when I'm in pain, idk why), it only intensifies. And trying to use the bathroom doesn't help either, seeing as pressure makes it a million times worse. I've tried OTC pain meds which work after the pain id gone and warm baths and bananas and all that. If someone could reassure me that I'm not dying from some sort of intestinal disease that starts out as this, that's be great. Am I the only one? Advice would also be very appreciated.
