Help..!!Sorry for the picture!

According to glow I'm 8 weeks pregnant. I'm having brown to red sticky spotting/light bleeding starting from Saturday. I went to ER on Sunday, they said my hormones and sonogram show about 5 weeks pregnancy, sac is small and empty. I am having repeat blood work today to confirm hormones. But I had this clot pass through recently. Is it my little blueberry, I lost? I don't have cramps or anything yet? But I'm freaked out as hell. Please help.
