MISCARRIAGE? WITH PHOTOS

My period was late 5 days. On day two of being late I spotted one drop of very light pink discharge/blood. On day 4, I spotted light brown twice while wiping. Hoping it was implantation bleeding and unable to wait I took a test which came back positive. The next day, day 5, I began bleeding very heavily (saturating thru panties onto pants) with lots of clots. I feel almost sure that this is an chemical pregnancy/early miscarriage but just wanted some other opinions to confirm my speculations.
