Implantation?

I'm so confused. Glo says AF on July 2nd but if you go by my 28 day cycle history lately then its due July 5th. Last night I did a cervix check and had one tiny drop of pinkish red blood on my fingertip (only noticed it when I put it on toilet paper) it was only a spec maybe a tiny bit more..

I have no idea when I would have ovulated my cervix is veryyyy short soft high closed and having a lot of lotion cm .... Any ideas? Someone give me insight pls
