Question!

I'm having milky discharge, all I want to do is sleep, and my breasts hurt terribly bad. I had unprotected sex the 14th, 15th, 21st, and 22nd. Possibility of precum on the 14th and 15th but on the 21st he cam directly in me I believe twice. My period is due on the tenth so I'm not sure if it's Pms but I don't usually get pms this soon and my breasts have never hurt this bad. Could I be pregnant?
