Cm question!

Usually I have lots of creamy cm leading up to af, because it stays white then starts getting tinged a pinky colour and then I bleed... this month (tmi) when I pull my finger out there’s not much on there at all, just a little bit of white thick sticky cm. could this be a good sign for me or do I have to have loads of creamy cm before a bfp? Has anyone ever had dry/sticky cm before a bfp?
