Should I test?

Due for my period tomorrow. I usually start having brown discharge day before it starts, but not this time. I have been cramping, which I usually do before I start my period, but these are a little more intense than usual. I also noticed when putting on lotion after the shower how sensitive my nipples are. Idk if I'm reading into these little things too much. Usually when I test it comes back negative and I get AF within hours.
