Spotting or miscarriage?

Hi, I’m about 5/6weeks and I found out that I’m bleeding. Bleed with cramps. Red blood. Changed pad once. Similar to period. I have experienced miscarriage before (about 4 months back) and previously I saw clots. This time round, no clots just bleeding and cramps.. like period. I’m going to visit the doctor tmr but the constant worry is there. Any words to calm me down? Anyone faced similar issue? Do share!
