I am now 3 days late and have had cramping and backaches for 3 days but no sign of my period. I took a clearblue digital pregnancy test last night at about 10 pm and it was negative, but I still don’t have my period. Today I had a hush of watery cm with a brown tinge to it when on the toilet paper. Has this happened to anyone else? Did you end up being pregnant? Could the test have been wrong?
