Miscarriage?

So I had what I thought was a faint positive 5 days before missed period yesterday. Well today I had a bunch of blood gush out of me. Thought it was my period. I just went to the bathroom and when I wiped a glob ( clot ) was on the toilet paper. I’d only be 4 weeks along. Can anybody tell me if it looks like a miscarriage or maybe just a blood clot from my period? If so, comment and I’ll post the picture! Thanks in advance!
