Need help/advice

Sorry this is kinda lengthy. Ok so last Monday I started spotting which didn't cause any alarm since AF was due on or about that day. Anyways that night I started bleeding heavily, passed a lot of large clots, pretty much freaked me out. I'm rh- so I figured this is most likely a early miscarriage (it's happened before) due to my blood type and was probably going to pass naturally. It was a very painful 3days or bleeding then it stopped as fast as it came. And now on Monday I started spotting bright red again. Not bleeding heavy just when I wipe. It looks like it's stopped now as I have a brown discharge when I wipe now. Ugh I don't know what is going on. I've never bled days after miscarriaging or having a period.
