8 days before period, strange CM

I have 3 kids already 13,12 and 7. I am TTC with my new partner.

My period was December 6th first day...

I apparently ovulated the 21st.

Today I am 8 days before my period is due and I experienced small amounts of stretchy cm..

The day prior to my Ovulation I had twinges on one side some dull ache kinda feeling. Thinking I ovulated. It seemed right on time...

Sometime later I did experience light pink discharge. Which was odd for me.

The last while I have been so tired and achy. Like so tired. Yesterday I had dull cramps. Stronger than earlier when I had em around my Ovulation.

Then today 8 days before my period is due I got that weird CM.

This is all odd?

Can you ovulate that late? Or is that possibly a sign of very early pregnancy?!
