What’s the deal with CM post ovulation?

I had an increase in creamy, sticky CM and I’m 6 dpo. I’ve read this is typical around cycle day 16-22 as your body prepares for menstruation. Could this be a sign I didn’t conceive this cycle? I have had this CM during this cycle time in the past. Anyone else have this kind of CM during this phase of their cycle? Thoughts on how it may related to TTC?
