My period pain is at an 8.

🌈J
My menstrual cramp pain is usually moderate....about a four on a 1 to 10 scale (10 being the worst). 
But the past two months, the average pain number is 7 and peaking at 8. 
I've tried Tylenol, heat, masturbation, exercise. I can't take NSAIDs. I also have a Mirena iud. 
Went to the doctor (not my normal one though) and he prescribed Tramadol. I took one and it has just taken the edge off (which I'm thankful for) but why does my uterus hate me so much????
Any tips I haven't tried? Because I will try anything.
