Ovulation on CD 13 or CD 15? Chart Included. Thanks!

[Jessibell2289]

So I got a positive OPK on both CD12 and CD13. I did not temp on CD 13. FF puts my OV at CD15. So its possible I ovulated anywhere between CD13 and CD15, what do you think? I'd be 11-13DPO. I had a drop this morning but no AF and no cramps. I discarded this morning temp due to my belief that the thermometer is going out. I'm getting a higher reading on a different one.

Here's my chart, Thanks!

I think FF is correct....you can ovulate up to 72 hours after your last positive opk
