Bbt help

The last month and a half my Temps have been extremely sporadic but the last 2 weeks they've pretty much leveled out, does that mean I have a chance now to actually ttc? I don't believe I ovulated last month (no positive opk)

Also I'm 1-3 days til my expected period and glow never gave me a coverline this month. Doesn't that mean it too didn't detect ovulation? FF gave me one but I'm not so sure about it.
