Chin acne that appears every menstrual cycle

I am so stressed because large pimples pop up on my chin every time my period starts. I read somewhere that breakouts around the chin indicate problems with the uterus or digestive system; is that true?

Getting anti-inflammatory injections at the dermatologist only provides temporary relief, and the problem recurs every month, so I want to find a fundamental solution. Has anyone overcome pre-period skin trouble through lifestyle changes or supplements?
