TTC #2, AF due soon!

I am due AF May 28/29, CM is thick-ish, creamy and sticky. I'm ttc #2 and not really tracked anything before. I ttc for 5 years (on/off) before accidentally falling pregnant once we decided to take a break after I landed my dream job... Convenient?! This time I'm really trying as my son is now 2 and I want a good age gap! Plus I'm getting older. 
​It's funny how the moment your not fussed about pregnancy it happens but you yearn for it and it doesn't!!
​What should my CM be like this close to AF?? I've POAS twice over the last 2 days each in the pm and got bfn as expected but just like the excitement. 
​Any comments appreciated and would love to hear your stories!
