Need advice

🌸🌼🌻

So I am 4 days on my period and I had brown spotting 3 days before my period. I am super tired and I not sure if I should test to wait it out. I took a clear blue digital test on Tuesday which was supposed to be the day my period started and got a not pregnant so I’m not sure what to do ? We have been trying for 4 years so that’s why I’m not sure if I want to test I don’t want the disappointment again.
