Spotting

Need advice. We've been TTC for five years now. I was really irregular for a long time. For almost a year I've been regular although still no baby. At 32 days this cycle I started spotting and have been for almost five days. But no period. What do you think it means. I'm afraid to take a test because it's always negative. Not feeling anything like pregnancy or periods. My husband said I don't even smell like a period. He said I don't even smell like me.
