Amniotic Fluid leak or am I paranoid?

Courtney • Anthony’s Mama! 12/08/2018

I’m 33/5. I’ve noticed being a bit more wet down there. I can’t tell if it’s discharge or if it could be a leak! I put on a pad and what was on there was a light brown, but odorless. I don’t want to freak out over every little thing but I am. I have an anterior placenta and have already had to go into L&D twice to get monitored. Any advice? How I can definitely tell between discharge or fluids?
