Chest pressure and pain between the v shape of my ribs?

kaya
Today is the third day of my period and I am extremely heavy. Ever since about 11:00, I have been having really painful pressure in the center region of my chest song with pain in the range of my diaphragm. I have this all the time during my period but I don't know what causes it or what it is. Any ideas? Is this a symptom of any kind?
