Normal Bleeding or M/C???

I would be 6 weeks today. AF would have been due Saturday and didn't show Sunday I had light pink/brown spotting only once when I wiped. Monday around 2-3am I got up to use the bathroom and passed a pretty big sized clot had no cramps at all. I put a pad on and went back to bed when I got up I had heavier bleeding no more clots or tissue and no cramps still. Today it's dying off still no cramps. My breasts are sore still. Just wondering if anyone else had something similar and was still pregnant.
