1. How Conception Normally Works

To improve fertility, it’s essential to understand the basic mechanics:

🔹 1.1 Ovulation

• Happens once per menstrual cycle

• Usually between day 12–16

• The egg survives 12–24 hours

🔹 1.2 Sperm Survival

• Sperm can live 3–5 days inside the reproductive tract

• This makes the fertile window longer than most people expect

🔹 1.3 Fertile Window

The most fertile period is:

• 5 days before ovulation

• The day of ovulation

2. Signs You’re in the Fertile Window

From dry → creamy → egg-white/stretchy (most fertile)
