Does this look like ovulation?

I am new to this. It's only my second month charting. I don't check CM unless it's obvious and I don't use opk's. Not currently ttc but it wouldn't be a bad thing if it happened. Just would really like some input. FF says possibly cd16 but then I had a significant temp decrease this morning (FF makes it look like it wasn't the same time as usual but it was literally 5 mins earlier than normal because I woke up before my alarm). Any advice??

Thanks so much all!!!
