CM day before period due

Hi all,

Just looking for some advice.

My period is due today (still had nothing) I had one day spotting just over a week ago I’d say, and when I say spotting, went to toilet once, had hint of pink then that was it.

My CM is still very much watery with slight cloudiness to it.

Think it’s to early to do a test yet, just wondering if anyone else has had this, my period sometimes comes at different times due to PCOS so hard to track

Anyone else had this?

Thanks!
