How to Increase / Decrease Chances of Pregnancy

🔄 1. Tracking Ovulation (Key for Timing)

Ovulation is when a woman releases an egg, typically 14 days before her next period. The fertile window is the 5 days before and 1 day after ovulation (6 days total).

🔍 How to Track Ovulation:

Method	Description
📅 Calendar method	Track periods for a few months to predict ovulation (day 12–16 of cycle).
🌡️ Basal Body Temp (BBT)	Slight rise (0.5–1°F) after ovulation. Track daily with a thermometer.
💧 Cervical Mucus Check	Fertile mucus is clear, stretchy (like egg whites) — means ovulation soon.
🧪 Ovulation Predictor Kits (OPKs)	Test urine for LH surge, which peaks ~24 hours before ovulation.
📱 Fertility apps	Apps like Flo, Clue, or Natural Cycles help track and predict ovulation.

💡 2. If You Want to INCREASE Pregnancy Chances

✅ Tips:

• Have sex during fertile window (especially 1–2 days before ovulation).
• Aim for sex every 1–2 days during fertile week.
• Avoid smoking, alcohol, and stress — all reduce fertility.
• Maintain a healthy weight (for both partners).
• Consider taking prenatal vitamins with folic acid.
• The man should avoid hot baths, laptops on lap, tight underwear, and heavy alcohol or drug use.

🚫 3. If You Want to AVOID Pregnancy

Without contraception, it’s risky — even timing methods can fail.

Options:

• Condoms – 85–98% effective
• Birth control pills – 91–99% effective with correct use
• IUDs – >99% effective
• Fertility awareness (natural method) – 76–88% effective with perfect tracking
• Emergency contraception – Use within 3–5 days of unprotected sex

Let me know your goal (trying to conceive or avoid), and I can guide you more precisely — including tips, apps, and mistakes to avoid.

If you want to avoid pregnancy naturally (without birth control), it’s essential to avoid unprotected sex during your fertile window — the days when you’re most likely to ovulate and can get pregnant.

📆 Safe & Unsafe Days (Fertility Awareness Method)

🔍 A typical menstrual cycle is about 28 days long (though 26–32 is normal).

Here’s a general breakdown for a 28-day cycle:

Cycle Day	What’s Happening	Risk of Pregnancy
1–5	Menstruation (period)	Low (but not zero)
6–11	Pre-ovulation	Low to moderate
12–16	Fertile window (ovulation)	High risk
17–21	Post-ovulation	Moderate to low
22–28	Luteal phase (pre-period)	Low

🟠 Avoid unprotected sex on Days 9–17 to be safe, as sperm can live up to 5 days and ovulation timing can vary.

---

⚠️ Important Notes:

• Sperm lives inside the body for up to 5 days.
• Egg is viable for 12–24 hours after ovulation.
• Ovulation doesn’t always happen on Day 14 — it can shift with stress, illness, or irregular cycles.
• If your cycle isn’t regular, this method becomes riskier.

---

✅ To Improve Accuracy:

Use a combination of methods:

• Use an app (like Flo, Clue, or Natural Cycles) to track your period and predict fertile days.
• Watch for cervical mucus changes (slippery, clear = fertile).
• Use ovulation test kits (OPKs) if you want high confidence.

🛡️ Natural Birth Control Isn’t 100% Safe

Even with perfect tracking, failure rates are around 12–24% per year. For higher protection:

• Use condoms during fertile days (or every time).
• Or consider hormonal birth control, which is 91–99% effective.
