Why do I have the worst week every time on my period-AIO

Every time im on my period my mom becomes the most annoying person ever sje only complain when im on my period whether she knows that I am on my period and also when she doesn't know I know its not my hormones im not dumb like for example normally she wouldn't complain abt me relaxing when im the one who does most of the house chores and I am literally the most supportive to her nearly in every way and I noticed that I get my period also during final exams. I AM DONE WITH THIS BULLSHIT

Am I crazy?? Or am I overthinking it??

Also I know that life is full of good and bad days but I'm rlly noticing this pattern
