Bleeding and positive tests

Normally I have 30-day cycles... To the day. Last month my cycle was 40 days and this month, since I wasn’t sure when I’d get my period, I started testing early. For the past five days I’ve gotten faint positives (I’ve taken two digitals and both said no). Yesterday I had light brown when I wiped but I figured it was old blood. Today, cycle day 40, I wake up with bright red bleeding. The pregnancy test also said positive, though still a little faint (but darker than others). I even took a blue dye test and it said positive. Am I miscarrying? Is bright red normal? No cramps or anything. Help??
