Cervical mucus question

Alix
So I'm either 10 or 11 dpo.. AF is due shortly..
I haven't had much cm in the last few days.. Mostly just light creamy / very wet feeling.. Today I wiped and there was a medium sized amount of thicker creamy cm tinged very light pink.. I've been having some cramps off n on and my bbt is fluctuating a lot (low grade fever in the evenings and .40 degrees lower in the mornings).. Boobs aren't as sore as they have been mostly now just on the sides and under the arms.
Thoughts.. thinking it could be AF.. I normally never spot it just shows up full force.  I am pretty much thinking I'm out but that glimmer of hope is burning..
Thanks!!!!
