12dpo cervix softening?

Melanie

I'm 12dpo & all my tests are BFN but suddenly today my cervix is softening & getting higher??? Why would that happen? CM is thin but sticky/creamyish.. not much really. I usually have sore boobs from ovulation until my next period but they aren't sore for almost a week now. I literally have no symptoms & AF is due tmrw. I usually cramp for 2 days before she arrives but still nothing! I just wanna know what's happening! No signs if she's coming & no signs if I'm gunna get my BFP.
