Late period ???? I just need some help!!

Hey girls, so I’m needing some help to calm my nerves a little bit. My period is late 8 days now, and I’ve had some pretty crazy mood swings, fatigue, headache, sore boobs, stomachs ache, Nausea and hot flashes, with some of these symptoms I thought my period was coming but it’s now & days late... I tested on the 5th day of my period being late, should I wait till day 14 to test again???
