How accurate is FAM ?

[FirstCub4Bear]

I'm 9 dpo and have light brown/pinkish CM.

At 7 dpo i had a very tad bit little bit of pink CM. at 8 dpo, I had one streaky/dark blood (purple) CM and off and on light brown spotting the rest of the day (not enough for a pad)..

I'm starting to wonder if I'm really five days away from AF, or if it's due tomorrow. I have long cycles and this month relied on FAM and my OPK (see chart). Both put me at a point where I'd be  9 dpo today.
But what I don't understand is why FAM picked up on that date (CD 31) instead of CD28, which also had a temp rise right after it that seemed to stay up.
Can someone look at my chart. Is it possible I O'd on CD 28, making AF due tomorrow, or does it look like FAM is right?
Can FAM be way off?

THANKS!!!!!

FAM is fertility awareness method and the chart/Web site does it automatically and puts a cover line. Basically, it'll show you the day of ovulation and if you're temps stay above that coverline you're in good shape. The Web site put FAM at CD31. I got a positive OPK actually on CD30, but the chart made O based on that CD31 because I guess the ovulation predictor says it'll be within the next 24 hours or so.

So, yes. Just wondering how accurate FAM is. I hope it's right and AF due on Sunday

I went to your profile and looked at your ovulation tracker....Tina is a better chart reader than me, but based on your temps,  I would think that you o'd on CD28.  You got a positive OPK on the CD31?

I am not really sure what FAM is, sorry about that...
