When did I ovulate??

On CD15 I thought I felt an ovulation pain on my right side, but it could have been random. Started getting EWCM on CD14, tested positive opk on CD18 and got a darker line on CD19. My temp looks like it spiked today but not as high as it should be so I'm a bit confused.

I just came off the pill and this is my first cycle so I expect some irregularity. I know the first positive opk is supposed to be a day before ovulation but I think I ovulated yesterday after my second peak test (CD19). Does it look like that to anyone else? Maybe I need to see how my temp goes the next few days to see if I actually ovulated this cycle.
