Hi there! Oh girl I feel like I know how you feel. When I had my m/c, it started with pretty light bleeding too, so every time you see blood, your heart sinks, like "this is it, it's over." But so far so good for me this time. I had my anatomy scan last Monday, and I'm hoping to hear from my Dr this coming Monday that the SCH is GONE. So sorry you're having to deal with this, and it is super scary, but it seems like things turn out okay most of the time.
Also, so sorry to hear of your loss.
Really praying that this will be your rainbow.
