are u taking EPO? I have a question

Jolene • Momma of a beautiful girl Kinsley Anne born Jan 18th 2016 and due with our 2nd girl Maddison Reece due May 15th 2017
So I've been taking EPO, and I wear a pad for the obvious reason, but anyways I just went pee and checked my pad, and I noticed it was almost light brown tinted, u know usually it's yellow like pee, and it's just in one spot that looks brown the rest is yellow. I wiped and it was yellow tint. But I'm having a hard time telling if it really is brown tinted. Have any of you had it almost look brown tinted in a spot?? Or just yellow?
