Really Light Period?

Chelcie
Not sure if it is just me, but my last period or maybe I shouldn't call it that was really weird.  First off, my periods have always been irregular, but lately, I thought it was finally becoming regular.  Anyways, on New Years <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> I started spotting after not having a period for a month. I thought, ok it was finally here, but now I am not so sure. New Years <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a>, New Years day, and most of the next were spotting days. The rest of the third day and most fourth day were light flows, I used a regular pad and I didn't need to change it. Then I spotted for part of a day. It might be TMI, but all except for one time going to the restroom, it was brown in color.  I did test after the first month of no AF and it was negative.  Not sure what is wrong, if anything, but I was a littled weirded out since this never really happened before.  I'm thinking maybe I should test again, but I hate the fact that it keeps coming back as negative.  It really makes me sad and kind of depressed.  Has this happened to anyone else?
