Pink. Period or prego?

Faith
My husband and I are trying for baby #1. This is our second month trying, so I'm hyper sensitive to anything going on with my body.  
I just had creamy pink discharge and mild discomfort in my lower abdomen. My period is due next week. Usually I get very brown discharge before a period... Never pink. Could this be an early pregnancy sign? And is it too early to take a pregnancy test
