missed period

Yesenia

I have 4 days with very high cramping. It feels like if I was on my period but I'm not. I have very sore breast and I feel tired, my back is killing me, and the cramps hurt so much. I'm 3 days late now but I'm scared of taking a test and get another negative. We've been trying for a year now. Anyone has had an experience like So? Should I worry or wait to take a test? Or just hopefully wait for my period? Thanks
