Can anyone tell me...

When you see temp dip on bbt chart does it mean that ovulation HAS happened, is GOING TO happen or is happening that day. I had a temp dip last tue (CD14) then rise on Wednesday & temps have stayed up, does this mean I ovulated Monday, Tuesday or Wednesday. I only DTD the Sunday before, the Wednesday & Friday, think I’ve missed it again

Yeah that was Tuesday, I’ve only been doing it for a week so not got a whole month to compare & only did it out of curiosity as found a built in app on my phone. I’ll try to attach pics

I’m aware there’s not a lot to go on, predicted ov day was meant to be 31st (CD17) DTD 26th, 29th & 31st. OH was away for work on 27th & 28th anyway. Just annoyed if I’ve missed it by a day
