Definitely get checked. My gp was more concerned about the bleeding being an ectopic pg than a m/c.

Mine turned out to be a missed m/c tho only measured 5 wks at 7 weeks. My m/c was just like an extra clotty period.. not much pain. And it can take a while for hcg levels to drop too. Unfortunately m/c happen even when we've done everything right

I truly hope everything is ok for you. I had muddy brown bleeding for over a week with my Ds so like you say it doesn't have to be a bad thing. Will be thinking of you *hug*
