Help please. Period and positive pregnancy test?

So I have 2 kids already so i feel so stupid now. Last Thursday I had a positive test. When I did the clear blue digital friday morning it said not pregnant. So I used a diffrent brand that afternoon and it said pregnant. Saturday the test was still positive. Sunday I got my period. Yesterday (monday) I had lots of blood loss. Normally I have a long period, somewhere between 6 and 8 (sometomes 10) days. Wel.. my period stopped today. I have like a bit of spotting now. Yesterday the biggest tampon wasn't enough, today I only have a panty liner. And I did a test this afternoon, it still said positive.

Did I have an early miscarriage or am I pregnant? I am going crazy here (I was so sad the past few days and today I moved on.) The positive test and stopped period after 2 days are weird right?

It is a light line, but still there. What do you think?
