Chin acne... Is this really a uterine problem?

I get a huge pimple on my chin every time I get my period, and it's so stressful. I read somewhere that pimples around the chin are caused by a problem with the uterus or digestive system. Is that true?

I go to the dermatologist and get anti-inflammatory injections, but they only last for a short time, and they recur every month, so I'd like to find a fundamental solution. Has anyone overcome premenstrual acne through lifestyle changes or nutritional supplements? I'd appreciate it if you could share some information.
