9 days late no signs of AF or pregnancy

I'm so confused AF was due the 8th I'm now on day 45 9 days late and no symptoms of anything other than very dull cramps here and there and very little nausea the other day. My ov prediction was the 22nd i tested all week and got dark lines but never darker than the control line so I assumed I did not ovulate. SO was going away for work so I stop testing after the 28th he left the 1st of Oct. I tested every other day until Saturday the 14th all big BFN so disappointed 😔 I have a doctors appointment today I doubt I'm pregnant but praying i am but anyways want to know what's going on. Below is my chart. Any thoughts???? I'm going crazy here special With my SO being away
