Time to test?

El

My period is 5 days late, have had light/medium bleeding but its brown and stop and go, forsure not my period. My periods have been very horrible since I was like 12. I get severe cramps where I cant leave the tub and cry for hours. So im spotting painlessly absolutely 0 cramps but my back hurts a little bit and my nipples are super sensisitve. Is it time to test or do I give it a few more days?
