Light brown discharge

Laura • Pregnant with our rainbow babe :) Due Sept 17! ❤️
Hey ladies! I noticed on my undies today some very light brown discharge. I'm hesitant to even say discharge bc it's just liquid (as if I peed myself a little) but definitely darker than urine and I felt more wet down there than normal today. I'm almost 13 weeks and that concerns me. Anyone else experience this?
