Let’s clear this up: your fertile window isn’t a fixed date, and your app probably isn’t getting it right. The fertile window is the 6-7 day stretch when pregnancy is possible, but most apps use calendar math, not your actual biology. 
Here’s why that’s a problem:
1. Ovulation isn’t always Day 14
2. Cycles can vary, even if they’re “regular”
3. Apps are using a standardized calendar method and don’t track cervical mucus (the most reliable fertility sign) Cervical mucus changes in real time based on your hormones, and it’s the key to knowing when you’re truly fertile. That’s why kegg tracks it for you, so you can stop guessing and start syncing with your body. ✨ Accurate timing matters. #FertileWindow #TTCJourney #CervicalMucusTracking #FertilityAwareness #TryingToConceive #BodyLiteracy #kegg #OvulationSupport #Women #WomensHealth #TTC
