Sos help

So I’m 3( really 4) days late, cervix is high, and closed, and kinda soft. I took two test this morning and the first response looks negative, but if you hold a light to the back of the clear blue you see a faint blue line.

My boobs are sensitive, and I’ve been having cramps. But that’s normal with my period.

*Im NEVER late, ever. I have a regular 31 day cycle.

*this would be my second pregnancy

Any opinions?
