Side cramping and brown/pinkish discharge no pics

I am due on in 4 days but 2 days ago I got light cramping in my right side and brownish/pink discharge, I read that that could be signs of pregnancy but im not getting my hopes up yet. And unlike last month I took a test 4 days before, without the cramping, am just going to wait untill I'm due on and if I don't, them will take the test, so tired of getting my hopes up. And then spending the day upset because I'm not. Anyone else had these symptoms? I didn't know what they ment untill I ready online.
