BBT help please 😭

So I got a positive OPK on CD15, typically I temp at 5:30am. On CD16 I temped at around 4:30 and today I temped at 11am because I fell couldn’t fall asleep and didn’t sleep until 4am. Basically what I’m asking is, is this sky high temp accurate? It went from 96.96 to 98.06. I’m really anxious about confirming ovulation so any input would be great.
