Fertility Insights & Tips

📅 Understanding Your Cycle

Your menstrual cycle is divided into phases: menstruation, follicular phase, ovulation, and luteal phase. Ovulation typically occurs about 14 days before your next period (luteal phase).

⏰ Optimal Timing for Conception

The fertile window includes the 5 days before ovulation and the day of ovulation itself. Sperm can survive up to 5 days, while the egg is viable for 12-24 hours after release.

🔍 Tracking Fertility Signs

Track basal body temperature (rises after ovulation), cervical mucus (becomes clear and stretchy like egg whites near ovulation), and use ovulation predictor kits to detect LH surge.

When to Consult a Specialist

Consider consulting a fertility specialist if you're under 35 and have been trying for 12 months, or over 35 and trying for 6 months. Also consult if you have irregular cycles, known reproductive conditions, or recurrent pregnancy loss.
