CM during TWW question

[Acacia]

Just wondering who knows what CM is meant to be like towards the end of a cycle, both if you're UTD or AF is going to start?

I don't usually get much CM after O so don't usually take much notice of it (usually just watch my CM to work out O and that's it), but at the moment, I'm having variations between a small amount of creamy, sticky CM, and more slippery (occasionally pinkish) CM, almost like EWCM but pinkish/white coloured.

I have no idea whether this is normal for me leading up to AF, as I haven't monitored properly it before, and whilst I know that every woman is different, any experiences others have had with CM leading up to AF or in early pregnancy would be great!

TIA
