Why do people tend to flock around me when Im PMT'ing? I don't get it?

I swear down when ever Im going through PMT unaware of it at the time but anytime I have PMT that's when everyone flocks around me can the aura radiate confusion and attract people and Im always going through hell during that time, how can people sense that Im going through that? And then prompt themselves to come around me. Ive actually recorded it on the calender the only time people well family and its usually to start confusion but they come around me during PMT why pick that time? and now I definitely know before hand Im going to try and nip it in the but but because my Cycle is irregular its hard to know when it crops up.
