Ovulation Help Needed - PLEASE!! :)

BBT spiked majorly on Monday but OPKs weren’t positive until Tuesday (all day) & Wednesday morning. No obvious EWCM this month. I read that you ovulate the day before your temp spikes so that would have been Sunday not Monday, Tuesday, or Wednesday. ?? So, I’m not sure if I ovulated on Sunday or on Tues/Wed. What do you all think? BD on Sun, Mon, Tues, & yesterday so 🤞🤞 but would also like to have a solid idea of how many dpo I’m at now.
