Pregnant or not!

im.on TTC..when is the best time/ days of delayed to have a pregnancy test? Normally my period should start on june 1. Im almost 5 days delayed until today to be exact. And the signs im having is being always sleepy and tired also my breast sore so much that it really hurts... I dont want to think that i am pregnant even though i wanted to. The last time i waa delayed for a week. But then aftr a week it turns out im not pregnant at all... Me and my husband is really looking forward for having another little one... Thanks for those answers...
