My cycle is 35 days but glow predicted my period to come at 37 days and it didn’t come. I’m curious as to how to count how many days I’m late. from my regular cycle or from what glow says. Bc I’m that case my period is late for 5 days. I want to test but I also don’t want to get disappointed usually my period are spot on 35 days.. I just feel like I’m over thinking and I’ll get my period soon. My other question is when should I test to get a very accurate answer.
