Bleeding...normal or not?

Samantha • Mom to Greyson 👦🏼 💙 • Baby girl 🎀 due March 2019
I'm 6w2d and today for the first time I started bleeding. My stomach was cramping and I felt like something was wrong so I went to the restroom and sure enough there was blood when I wiped (it was brownish). I looked and saw a clot in the water when I got up. 
Then I went shortly after and more bleeding, this time red. Went again a few different times and still the same thing. 
I know implantation bleeding can happen but I haven't bled at all until now. Is this normal or am I possibly having a miscarriage? Your help is much appreciated...😔
