Black spotting. Am im glimg to miscarry?!

Brittany

Started yesterday morning. And when I get drops I also see tiny pieces of what might be tissue??? No cramping or any discomfort. I’ve lost two already around 5/6 weeks which is what I am now and one chemical around 4 weeks. I’m thinking I probably will. Anyone else have experience with this?? I’m getting my bloodwork done again Monday but of course have to wait all weekend.
