Endo weird symptoms

What weird symptoms do you have? Any skin conditions when your menstrual cycle starts?

I've been getting new and more symptoms each month I have my period. This month the day I started my period, I found these weird rash patches on my stomach area/ chest. They're red, circular, a little itchy and a little rough. Theyre not hives or eczema, but based on google, look more like Pityriasis rosea. I normally don't have any skin conditions but everything is changing since endo has picked up.
