Mind tricks!

My body is definitely messing with my mind! I took two test one at 10 DPO and one 12 DPO BFN for sure. I am now two days late and usually are on time or I can tell when I'm going to start. But of course I feel different this time. Idk I know in my head it's just PMS but waiting a week for no AF is going to kill me especially when I know she will come! Did I take the test early do I still have a chance? Not asking if in pregnant just want to know if it's a possibility.
