Ovulation date? Temping

I've been temping for most of this cycle, and I can clearly see the temperature rise that indicates that inoculated, but when? I had a positive opk Friday morning (tested am and afternoon Thursday, both negative; just so you all know my timeline). Glow and FF are giving me different ovulation days though. So did I ovulate before the temp rise (Friday) or the first day of the rise (Saturday)?
