Clear blue advance help?

Hey everyone

So I have been using clear blue advanced fertility monitor (1st time trying it) and I have been getting flashing smileys for 7 days now!

But Fertility friend thinks I ovulated 4 days ago based on my temp shift (BD’d 2 days before ovulation occurred according to FF) ... And Ive women up to very light spotting (not sure why this is as my cycles are usually longer and I’m only on CD27!)

Just a bit confused! Shall I just carry on with the clear blue and see what’s going on?! Could the spotting be ovulation spotting and FF is wrong? Or maybe my hormones are off and clear blue isn’t accurate??

Just wanted a bit of advice or anyone’s experiences using clear blue compared to tracking bbt l- any help or advice at all is appreciated !!

Thank you ☺️
