2 days late

I was suppose to start my period on tuesday but so far nothing. But also no pregnancy symptoms. Occasionally breasts are sore thru out the day. I have been waking every morning with diherria. I am to nervous to take a test tho. The only thing that gives me hope is that I pretty much always have these horrible insane pms symptoms for at least 1 week before my period which I have not had this month! Should wait longer to test?
