SOOOO LOST AND CONFUSED, 20 DPO, 6 DAYS LATE.

Summer • Had a TR Jan 4th 2016, TTC #1 in my new marriage.
20 DPO, 6 DAYS LATE. NOT TESTING UNTIL TOMORROW AGAIN. TESTED ON SUNDAY AND BFN. I CANT FIND ANY CHARTS THAT LOOK LIKE MINE. I HAVE NO IDEA WHY MY TEMP WOULD KEEP JUMPING LIKE THIS. Last night I got very emotional. Thought that my period was showing up late but now this. Anyone have any ideas?
