What cm is this could possibly ovulated late?

so in Thursday I had a little bit of 🩸 come out it wasn’t much it was very faint red pink ish colour but very wet if you get what I mean 😂 then on Friday and Saturday it was very dark and literally nothing there only when I wiped… I was due my period on Sunday… I did a test today and it was negative… there wasn’t even a flow and I had no cramps… never had this before? Now I have this cm I was trying to see my position of my cervix it’s high and soft xx
