Late period?

I typically have a relatively regular period. Up until this month, I got my normal bloating, sore breasts, but no cramping like I normally have. I didn’t think much of it until I was a day late. I decided to test. It came back negative. I still wasn’t too concerned until two more days passed and I still hadn’t gotten it. I tested again at 3 days late and it also came back negative. Now here I am, 6 days late. Should I test again? Am I overthinking this?
