Pinpointing ovulation..... Help!
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? 
Glow says yesterday

Fertility friend says 10/31

Any thoughts?
