I'm seeing a valley before or after my predicted fertile window, what should I do?Updated 20 days ago

kegg's fertile window prediction is a helpful forecast to highlight the most likely timeframe your fertile valley, or the dip in your impedance trend which occurs during your fertile days. Here’s why you might see a valley (a drop in your kegg readings) outside your predicted window, and why that’s perfectly normal.

Understanding the Fertile Window Prediction

• First Cycle: The prediction is based on the information provided during account set-up. During the course of this first cycle, kegg is hard at work learning about you. Help kegg learn more about you by entering past periods in your Calendar in the kegg app. 

• Future Cycles: The algorithm refines your predicted fertile window based on your previous kegg data trends, including your impedance trends, periods, and personal details

The goal of the forecast is to give you a helpful heads-up, but your body’s actual fertile timing may vary cycle to cycle due to factors like stress, illness, travel, or hormonal fluctuations.

kegg detects changes in cervical fluid, which can shift due to multiple reasons, not just ovulation. These valleys reflect real-time changes in your vaginal environment, and here are common scenarios where this happens:

• Early Cycle Dips: Many users notice a small valley shortly after menstruation ends. This doesn’t indicate fertility (unless within your fertile window prediction). 

• Luteal Phase Dips: Some users see a valley or bumps and dips in the luteal phase (after ovulation). This is another natural variation and doesn’t indicate a second fertile window. There are numerous hormone changes during the luteal phase of the cycle with expected cervical mucus changes throughout.

• Delayed Ovulation: Sometimes the fertile valley forms later than predicted. Many factors influence our cycle regularity, such as stress, illness, and travel. By watching your impedance trend, you can be sure you don't miss your most optimal opportunities to time your trying to conceive efforts.

• Irregular Cycles or Anovulation: If ovulation is delayed or doesn’t occur, your body may attempt ovulation again, leading to multiple valleys in one cycle. This is more likely if your cycles are irregular or affected by external factors.

The impedance trend reflects the real-time changes in your cervical mucus. 

• If you see a downward trend in your readings about 3 weeks before your next expected period, this is often a sign that your fertile window is opening.

• The valley corresponds to your most fertile mucus—stretchy, slippery, and sperm-friendly.

Timing intercourse or insemination during this actual valley can increase your chances of conception.

Seeing valleys outside your predicted fertile window is normal.  Use your kegg trendline to identify real-time changes in your cervical mucus, and watch for the fertile valley to form during or near your fertile window prediction. Don't be alarmed if you see bumps and dips before and after that. That is perfectly normal!
