Cervical position

Today I’m 14DPO (Af due today) all bfn’s up until yesterday and I didn’t even test today because I was sure af was coming, well she hasn’t shown her face and she’s due today! My cervix was high and soft all the way up until yesterday when it was low and firm, and now this morning it’s high and soft again. I know it’s not an indicator of pregnancy but I’m pretty sure if af was coming my cervix would’ve stayed low and firm? Every time I get my period I wake up to horrible cramps (that make me vomit) and heavy bleeding and this morning nothing. The only symptom I’m having this morning is sore breasts that feel like they’re going to pop if I even touch them.
