If there wasn't any cramping with your bleeding you're probably fine. I had some bleeding when I was pregnant with my son. If you're just 6 weeks, it's probably some implantation bleeding which is completely normal. It's always recommended to report bleeding to your doctor right away so they can check and make sure you're fine. They might say to take it easy for a few days. I would say there's nothing to worry about so don't stress yourself out about it. Just call your doctor tomorrow and i'm sure they'll tell you the same thing.

Good luck

Spotting some while pregnant is normal. It's when the bleeding is heavy that you need to start worrying.
