so confused ugh

so I was supposed to get my period on the 6th of September. I still haven't gotten it yet, I've taken 2 tests and they've been negative. My boobs are a little sore but I'm wondering if it's just because I'm feeling myself up to see if they hurt or not. My hubby and I aren't preventing but we aren't actively trying either. what should I do? go to my ON, just wait it out? *it says next period starting on 9/27 but that's because I keep pressing the 'My period is late button.*
