Why am I so emotional?

The last 3 days I have been crying for what feels like nothing, anxiety is the main cause I know But I don't know why I'm anxious. I took 2 1mg clonzepam today and still anxious and crying. My boyfriend came inside me multiple times on the 26th and 28th according to eve both highly fertile days and my period is due on the 10th, I never get PMS so early but could it just be my pms? But I have no other syptoms. Or could I be pregnant?
