Confused now!! 😐😐

Stacie
Here is logger chart but I am a 8 days late now! My chart doesn't show that as where I have been logging in each day my data, it has change my fertile windows and most O day to a week later now which u can see above as was b4 from 28th Jan to the 3rd Feb!
So does that mean I have ovulated later then I thought or my body just doesn't no what's going on?!
No AF and been testing each day for over 2 wks now and all BFN!
Also I've got a smear booked on the 24th (my birthday 😞 & 1st 1) so shall I say about it to the nurse if no changes till then?
