8dpo....

So, I'm 8dpo today. Had a massive temperature spike this morning but today I'm getting a lot of creamy cm...I never usually get much cm throughout the month really. Got EWCM this month though which was good. 
Anyway, is this normal? Lots of creamy cm at 8dpo? I got bfn on test today :(. 
My breasts are tender and my nipples are burning!!
