Understanding Your Fertile Window

The fertile window is the time during your menstrual cycle when you're most likely to conceive. This window typically occurs around ovulation, which is usually about 14 days before your next period.

Key factors that affect your fertile window include:

• Cycle length (average number of days between periods)
• Ovulation timing
• Sperm viability (typically 5 days)
• Egg viability (typically 12-24 hours)

Ovulation Calculation

Ovulation typically occurs about 14 days before your next menstrual period. Our calculator estimates this based on your cycle length and last period date.

Signs of ovulation include:

• Mild pelvic pain or cramping
• Increased cervical mucus
• Slight rise in basal body temperature
• Changes in cervical position

Tracking these signs can help you identify your fertile window more accurately.

Conception Window

The conception window is slightly longer than the fertile window, accounting for sperm viability. For most women, this window is about 6 days before ovulation and 1 day after.

Key points about conception timing:

• Sperm can live in the female reproductive tract for up to 5 days
• The egg is viable for about 12-24 hours after ovulation
• Timing intercourse during the fertile window increases your chances of conception
