Help?

On CD 15 my CP was high, soft and open.

On CD 16, it was still high, but firm and moderately closed??

Did I ovulate on CD 15? Or on CD 18 like they estimated? I do not use OPKs or bbt track. I have very limited funds and run around a lot all day.

If I O’d on cd 15 wouldn’t that make me 5dpo instead of the 2 dpo from cd 18?
