Late period.

I was suppose to get my visit from AF last Monday, and she still hasn’t showed up. I have taken 2 pregnancy test (in the afternoon) and they have both been BFN. I have been 1-3 days late before but nothing like this. I scheduled an appt with my dr but it’s not until the 15th. I’m including my chart, but my partner and I did BD on two of my medium chance days. So I’m wondering if it’s possible I could be pregnant but needing to test first thing in the morning? Suggestions, advice. TIA
