Spotting at 5 weeks 2 days

Tiffany
Hi ladies,
I just started spotting this afternoon: dark blood with "small pieces of particulate" in it, and I see it only when I wipe.  Has anyone else experienced this and gone on to have successful pregnancy?  I've already had 2 MC this year and feel like just got shot out of the sky.  Anybody's feedback is appreciated.  I'm afraid.
