Really need someone experienced with btt.

Summer • Had a TR Jan 4th 2016, TTC #1 in my new marriage.
I've been btt charting for 7 months now but I've never seen any of my charts look like this. I'm pretty regular every month 27-29 days 12 day lp.I've never gone this long without a period and I got a BFN yesterday. This month is taking me for a loop. 2 apps ff n glow say I'm 3 days but ovia says I just ovulated??? Any advice is appreciated.
