Confusing month

This month I have been feeling very tired boobs feel heavy so I did a test around on the 22nd ( I was due on on the 26th) and the test came back with a faint positive, my period was 4-5days late and I started to bleed this morning at first it was a brownish blood then went to heavy bright red blood and now it has slowed down has anyone had anything like this ? Could I still be pregnant or was I never in the first place ?
