spotting

Amy • Married my high school sweetheart. We have 2 wonderful 4 legged children, Tinkerbell and Rocket. I love my little family
I am very nervous. I am 6 weeks and 5 days today but just had spotting. It was very light brown and watery. It's a Friday night so I can't call my doctor until Monday morning. Should I be worried? I don't want to read too many articles and make myself more worried. Advice/help...? Thank you.
