Charting help please!

I’m so so confused, I’ve been getting negative opks but my chart is saying I o’d on Saturday? I was all over the place! First time temping and all, and was temping between 4 am and 7.30 am. I get up at random times during the night often to go pee so I temped whenever. I also missed temping on Monday but I still got the ch, is this at all accurate? We bd’d Saturday and Sunday/Monday-ish (midnight) so not sure if I’m out this month or is it too early to tell? So overwhelmed with everything! Thanks in advance ladies.
