Freaking out

Beth
Hi I'm 6w1d. Last night I started spotting. It started off red, a little darker red than normal, but still red. It was light, and continued to get lighter and turn more brown throughout the night. This morning it was brown and barely there. I've had no cramping or pain. I'm just a little worried. I never so much as had the tiniest spot when pregnant with my son so this is very scary for me!!! Any thoughts?
