Hi everyone, question for you. My period is 7 days late and every pregnancy test I have taken has come out negative. For this whole month it kept feeling like I was going to get my period but nothing ever came. I've been regular all my life and have never missed one.

Before I head to the doctor, can anyone give me any insight as to what could be going on?

And I am not stressed, so I know that that is not a Cause

Thank you
