Early testing

I took a test today which was negative...I have 5 more days until my period is due and didn’t realise you were meant to use first wee of the day when testing early. How much impact does this have? Is it worth trying again in a couple of days...I’ve had other symptoms including fatigue, horrible taste in mouth, sore boobs, but don’t know if I’m tricking myself into thinking I have these symptoms 🙄 x
