Am I overthinking everything?!

I am 2 days away from AF. I took a test earlier this afternoon and it was negative. I’ve been having slight cramping on and off for the past few days nothing too painful, I’ve been extremely fatigued and for the past few hours my whole back has been on fireeeeeee. We’ve been trying for nearly a year now and am praying this month is our month. Anyone have similar symptoms and negatives so close to AF but ended up pregnant or am I just overthinking it all?!
