Fertility friend chart - is it correct?

[Lozb8]

Hi I'm currently 15dpo If FF is correct (which I have to say always has been spot on!) My LP is usually 12days so I'm a little confused & wondering if the Oval day is correct?
This cycle is following an early miscarriage 😯

Sorry for your loss.

It could be right, the thermal shift isn't obvious but if you ignore a couple of outlying temps the crosshairs could be right.

The other option is you Od much later CD26.

Have you done a test?

Thankyou.
Yes I hadn't considered that. What made me think the crosshairs are correct is that every cycle the 3 days leading up to Ov, my temps stay very consistent & close together and don't jump around. That's usually my sign lol!
I did test today and it was negative and So it begins!..
