Have I had a miscarriage?

The top one was taken about 4 days ago. The bottom one was taken about 1 hour ago. Went to the hospital today with tummy pains. Had hcg bloods done. They were low they said. I'm 6wks+1 day due to LMP. Repeating again Saturday morning but I think I've miscarried already. Thoughts please? Xxx thanks xxX
