Did I really ovulate this month? FF says I didnt...

Hey ladies!
So, I'm tracking my temps with Glow and FF and they diverge regarding my ovulation. Glow says I'm on 15DPO, but FF didn't even mark my ovulation. If so, this will be my second anovulatory cycle and it worries me a lot 😰😰😰
Does it really seems that I've ovulated on CD 13? I had an OPK and it marked as positive, but I still have doubts due to the temps...
