Anyone else have discharge that was watery like pee?

Jessica
I'm 21 weeks, it's happened since I've been 16 weeks.
It just randomly comes out sometimes. It's yellow/dark yellow colored. NO ODOR NO ITCHING. 
Noticed if baby is low pushing on me it's like he will push hard and it will come out sometimes. 
Very watery like urine but I know it's not urine
