Will I go into labor soon?

Doreen • 18 year old momma to be, due in early April 2016 (9months pregnant) 💕
Hi ladies I'm 37 weeks along as of yesterday and for the past week I've been having cramps around my abdomen, Im nauseous, my stools have been looser, I've been feeling weaker (like I can't open my eyes and I can't walk cause I feel lightheaded), my discharge has been weird like one day it's dark yellow then another it's clear then there's none the next! 
Can anyone help???
