Pinpointing ovulation..... Help!

Jessica • Edd 11/9 #3 after losing 6 mo old daughter last July & having a tubal reversal in September. Hoping for a rainbow baby!
So normally my ovulation is obvious with the opk and then a big bbt spike..... This month bbt has been all over the place and glow and fertility friend are both predicting way different. Today I'm on cd 17, 3rd day in a row of positive opk.... What do you ladies think? Do either of these look right?

​Fertility friend says  10/31
