How did you know you were leading amniotic fluid without it gushing?

I just took a shower. ... put on a new pad and underwear and lied down. Out of no where I felt some liquid coming out and sat up. ... went to check it out and the liquid is tinted a bit yellow? I'm 38 weeks and 4 days.... not feeling any cramping yet either
