Possible ovulation

Taylor • Tue, Dec 02

I'm still new to recording my bbt and my temp was low yesterday and spiked up today according to Glow with the spike it means I could indicate that I ovulated. My husband and I are TTC and tomorrow I will be 2 weeks late, I've taken a few test but all were BFN. So my question is when your temp drops low does that mean your ovulating?
