FRER vs IC sensitivity

I'm currently on CD27. My previous cycles have been 28, 27 and 33 days so I'm not really sure when AF is due. I've just done an IC and it's negative, am I right to think there's no point in doing a FRER yet in that case?

How many dpo are you?x

What's IC? IME FRER is much more sensitive than the clear blue 6 days early one.

Some internet cheapies say they are sensitive but I'd trust a frer more

FRER are far more sensitive. FRER measure HCG at 6mIU whereas ICs measure it at 10mIU (apparently). I got my BFP on a FRER at 9dpo but didn't even get a hint of a line on an IC until 12/13dpo.
