Spotting/positive test

So I have had on and off brown spotting since last Saturday. Two times when I had a bowel movement there was blood. Not a whole bunch but enough. This morning I took a test because my period is suppose to start today.

I got a positive test. So excited and nervous due to the spotting as I had a miscarriage last winter...

Should I be really worried or could it just if been implantation spotting??? Help! So nervous 😐
