Cervical mucus sign of pregnancy?

Steff

On 5DPO I had CM to the point where it was on my underwear.

6DPO had some what but mostly when I wiped but barely noticeable

7DPO tested and was BFN which was expected

8DPO (today): again I have CM on my underwear and I peed some out. It was a ball of CM (TMI lol)

May this be a sign of pregnancy?
