Am I taking a miscarriage?? Tmi

Trap-Queen
I had positive opk on 6th and 7th.. I BDD.. I took this tests last week.. The results on the tests are not clear and I'm unsure if I was ever pregnant.. 
My period was due on Thursday & today I started bleeding quite heavily to begin with and today over the past 2-3 I've passed these? Is this a miscarriage?
