Pink spotting

Stephanie • 2 back-to-back miscarriages. Hoping to meet our rainbow baby due July 19, 2017.
I am 6 weeks & 4 days pregnant. Last night I noticed a small amount of pink spotting after wiping but nothing since. I have had 2 previous miscarriages and am terrified this might be a sign of another. Has anyone else experienced this? Am I just worrying to much?
