i have concerns, please help

For the past two weeks I've been feeling so fatigue, nauseated and pressure on my bladder when I either sit or stand.l amd spotted once, no where near my monthly. My husband and I have been TTC and I really hope I am. I'm 4 days late but right now I found some light brown spotting when I woke up and now light bleeding. Should I not bother with a test? Was it just already a false? I don't know what to do.
