Baby movements!?

Shania

I'm 28 weeks and I been having light cramping, thinking its PH and a lot of pressure in my lower stomach. Today the baby hasn't been moving a lot. Maybe 4 times so far today, it was only little kicks. I have a increase in discharge, like underwear soaked discharge and it has no smell but a yellow/orange tinte to it. Is this Normal for my 3rd trimester??
