Strange discharge.

So yesterday I went to the hospital because I had severe cramps, bleeding and I passed a blood clot (I though was the baby. Thank god it wasn't) and they told me I was at risk for a miscarriage. I don't have any stds or infections, but today when u got home from work I noticed a clump of discharge in my underwear. So I checked inside (sorry if tmi) and I got a whole bunch of it. It's grayish, thick (like a yeast) and it smells like copper. I've never had this before in my life. I'm also 7 weeks. Has anyone experienced this before?
