What is happening ? Pregnant or not ?

I am now 3 days late for af. (Today will be 4th) I took a hpt a day before af was due not sure if I had line eyes or not as I could see a vvv faint line on photo but not on test anyways tested again yesterday ( 24th) bfn. Last night I did a cervix and cm check had white milky cm, tinisest bit stretchy (sorry tmi) and when I checked cervix had tiny bit pink on it. I presumed af was going to start at last so thought no more about it but today( 25 th) there's absolutely nothing cm still same and I can't even reach my cervix its really high. I've had no sore boobs or any sign of af or pregnancy except slight cramping (usually i get intense cramping few days before af then when it starts) and nausea. Does anyone have any idea what the hecks going on ? I really thought af was going to start as it would of been quite a relief as I was starting to think something was wrong ( but also sad that I wasn't pregnant ) is there a chance I could still be pregnant ? I really don't know what to do.
