Tested 6dpo - negative but

Jenny

So I tested on day 6 post ovulation and had a big fat negative. Not a chance of anything faint. And now today is my expected date for AF and I have felt super nauseous and dizzy. Now I understand those can also be period related but they are not usual period pains for me. Just wondering if you ladies think I should test today or wait a few days to see if AF comes because of the prior negative ?!
