TMI TMI!!!

could this be AF coming? It seems more like discharge/CM to me. It's been very light, this is the thickest it has been so far. One app says AF was supposed to start yesterday & The <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow App</a> says it should start this Saturday. I need opinions please ladies!! Been trying for our rainbow baby for almost 4 months now...
