Seeing blood?trying not to freak out

Jill • Married to an amazing man. Have a beautiful handsome baby boy. Baby #2 is on the way.
So really trying not to freak out. I'm about 5 weeks pregnant and been doing good on everything. And today I went and wiped and found some blood. It's a lighter pink color. But I haven't had any cramping at all today. Should I be worried?
