bfn day Af due but went on to get BFP?

Hailee
Has anyone tested negative the day af was due then tested positive after? Af is due today and I'm cramping like she's coming off and on, but no blood at all and my cervix is so high that I can barely reach it and it's very wet and mushy feeling.....Any feedback or ideas?
Update: STILL NO AF!!!! Trying not to get my hopes up. I haven't been too stressed honestly, but tested negative today. My cervix is still barely reachable and even softer than before. Still closed!
