AF still hasn't showed

So I'm due for AF today and for now there's no sign of it showing my boobs are so sore right now and I felt my cervix and it's soft and closed I could barely reach it there's no blood on my finger at all when I stick it in I had light spotting 2 days ago and a bit mucusy light pink discharge yesterday I have been feeling a bit sick to my stomach and I havnt really been feeling well my fiancé says that I feel really warm sometimes I'm not sure what's going on
