Im scared

I'm scared, I'm 4 weeks 1 days. I started some light bleeding. I have a history of miscarriages, so any and all bleeding scares me. I'm not sure if its implantation bleeding or worse. Im trying to keep calm and find comfort in the fact that I'm not cramping and it's not getting any heavier. Anyone else with a history of miscarriages and ended up just having implantation bleeding leading to a healthy pregnancy?
