Bleeding at 8 weeks

Pax

I am 8 weeks and started spotting yesterday. At the beginning red and the brown. Went to the hospital. Blood test fine but couldn’t see the baby as the scan machine wasn’t good enough. I will have a proper scan tomorrow. But today I had a big clot and I am really worried. Should I go back to the hospital? Anyone experienced this kind of spotting and then everything was fine? Thanks.
