Brown discharge and no period

Hi girls! Ok lets see I am supposed to have my period on april 22nd. But the past two days I had supeeeer light brown spotting, and today I felt lik I was having my period, but instead I am havig just brown discharge with very little pink. I have cramps but not as frequent and as bad as I usually get them when I am in period. I had sex when I was ovulating, but the condoms we used were "dry" (hard to explain). Should I take a pregnancy test? Or maybe it could be something else. I never had something like this before.
