Fertility friend confusion

[maria47]

Hello ladies.. I am sure this has been said before here but i am really confused with ff's methods.. this month the advanced method says i ovulated CD9 (kind of impossible as i spotted on CD13 and had cramps thw day before..) but when i switch to all other methods none of them seems to confirm i have ovulated yet... what do you think?

The link to your chart isnt working, nothing comes up on the page... but FF can be wrong, its currently saying I'm 10 dpo when I tjink I am only 2 dpo... it was wrong gor me last cycle too, I'm changing apps because of it, I've found it quite unreliable
