Weird cramp in right ovary instead of period?

Guys, I'm getting a fairly strong cramp in my right ovary today. I'm one day late for my period (I'm always on time or early). I took a test yesterday but it was negative. It's a strong cramp but it's not an unbeatable cramp.

I'm having the *slightest* bit of EWCM type discharge with a VERY light brown tinge. Last night I had quite strong period like cramps but nothing happened.

I'm actually getting annoyed... Like can my period just start or is this going to result in a pregnancy or????
