Am I still pregnant?!!!?!??

my last official period was nov 7th.

on dec 5th I got a very faint positve test and again on the 7th but then on the 8th I start having heavy bleeding and passed a clot. it wasn't a full on period but close to it. then a few days after I had on and off spotting for a couple of days and just for the he** of it I took another test today the 18th and it came back a  big bold positive.

is is possible that I am still pregnant after the bleeding?why would the test get darker after I lost the baby and still be dark 10 days later.

i had a miscarriage and took a test everyday till it was negative and it  took 3 day to show negative and everyday I watch the line get lighter ( that was a few months ago)
