How to sync Myfitnesspal app

Talia • 33, Married 5 years to my best friend and blessed with a precious baby boy (13 months).Trying for Baby#2 this Spring!
I downloaded the myfitnesspal app and turned it to "On" in settings and don't see any info linked to Glow. Anybody know how to sync the two apps? Help would be much appreciated! Thanks! :)
