Fertile Window

So quite a few days ago I started showing eggwhite CM and entered the data in. my last day of fertile mucus was on the day Glow predicted my fertile window to begin. Kind of confused as to why Glow doesn't automatically change to fertile when you enter in multiple days of fertile CM. How long does it take? Luckily I use multiple apps for charting (TTA) but would love to be able to trust Glow :/
