Playing against ghosts

HI .
I’m a zerg player in diamond 2 .I’m having issues playing against terrans who go ghosts .The problem isn’t so much playing against ghosts.it’s spotting nukes. I played many games where I’m extremely ahead but cant engage because I’m constantly looking for nukes.I can post a replay of a game I played recently and if you look from my pov, you cant see the red dot on any of the bases .Any one else having this problem?
