Please Help

Yesterday marked day 5 or 6 of being late on my period so I took a test and it showed that I was in fact pregnant. We woke up this morning and I had what I thought was bloating discomfort but when I went to the bathroom there was bleeding and small clots. So we went to the ER and they confirmed I was pregnant but my HGC levels were at 9.67. We didn't do the ultrasound bc the dr said we wouldn't really see anything yet since I'm only at about 4 weeks. So we go back next week to check that. But after we went to CVS for tylenol and when I used the bathroom I passed a huge clot. Please tell me if this is a miscarriage, I just need to know.
