Does anyone else look for signs?

So I keep hearing this song what will be will be and that’s been my motto for the last year or so, then last night I had a dream of a bfp. Today I’m 3 days late and yesterday I took a test in the afternoon but was negative. I had this mild cramping/indegeation for about two days now and still no sign of af. Is it possible to still get a positive in the coming days?
