What are your thoughts ladies? I

So I was late and I am usually on time like clockwork. I took a pregnancy test at 5 days late and got a faint positive. Now at 8 days late I just started gushing blood out of nowhere and along with that I had super intense cramps that lasted for almost a minute each and hurt so much I had to hold my breath. Lot of dark blood and clots. Does anyone else think this is probably a miscarriage?
