What is wrong with me, my body does not seem "normal" anymore?

I've had some pink spotting a couple days ago.. I thought it was my period but it only lasted 2 days and was very light. I am still waiting on my period. (im 5 days late). Now I have a "golden" discharge? I have had unprotected sex this month but I don't have other "pregnancy symptoms". My breasts feel normal. I have had no morning sickness. No headaches. The only thing is my face broke out, and im more tired than usual. What else could this be?
