amniotic fluid

has anyone on here ever leaked amniotic fluid? if so what did it look like? I've been leaking something for 2 days and I figured it was just discharge at first but this is more than discharge. leaving bigger spots in underwear and anywhere I sit. before I start to worry/freak out and call my doctor, because I always do, I wanna know if I need to worry. this is like a yellowish creamy substance. this is my second pregnancy but I didn't have this the first time. so I'm already worrying.
