What affects conception
Timing, age, ovulation regularity, sperm factors, health conditions, and chance all play roles. Monthly probabilities cannot diagnose fertility.
When to seek advice
Clinical guidance is commonly considered after 12 months of trying when under 35, or after 6 months at 35 or older, sooner if concerns exist.
How to use this result
Use the estimate as a practical starting point, then track how you feel and adjust gradually. For medical conditions, pregnancy, medication use, or major training changes, consult a qualified health professional.
