Help, please! !

I had very light spotting for about 3-4ish days; very little pink mostly brown and watery looking. I stopped bleeding for 7 days and was getting ready to get a test. Started bleeding again, started with very little brown and watery again then transformed into dark red with clots. Does it sound like I may have miscarried without even knowing if I was pregnant? Would I still get a positive test if I took it?

Update: just took hpt, BFN. No faint or anything. I'm okay if I was never pregnant, but don't want to have a lost baby that I never got to know.
