pregnant or not?

I'm having so many pregnancy symptoms right now. I have swollen breasts, fatigue, cramps, a super light period so I'd say it's spotting, nausea, headaches, diarrhoea, mood swings and dizzyness plus even more 
I did a test 5 days late for my period and it came up negative when will be the best time to test again? 
I'm thinking test again when I'm 7 days late?
