Signs of Ovulation: How to “find my fertile days”
Ovulation is the release of an egg from the ovary, typically around the middle of your cycle. While many assume it happens on Day 14, the timing can vary depending on cycle length and individual hormone fluctuations. Recognizing ovulation signs can help track fertility or avoid pregnancy naturally.
Common Symptoms of Ovulation:
- Cervical Mucus Changes: The mucus becomes clear, slippery, and stretchy—similar to raw egg whites, which helps sperm travel.
- Increased Libido: Many people experience a higher sex drive due to the estrogen surge.
- Mittelschmerz (Ovulation Pain): Some feel mild cramps or twinges on one side of the lower abdomen.
- Basal Body Temperature (BBT) Rises: A small but noticeable increase in resting body temperature occurs after ovulation.
- Cervix Becomes Softer & Higher: Internal cervical changes make it easier for sperm to reach the egg.
Tracking these symptoms along with period dates helps pinpoint ovulation and fertile days.

How to Calculate Your Next Period Using LMP
What is lmp in medical terms – Last Menstrual Period (LMP) method is one of the easiest ways to estimate your next period and ovulation.
- Formula: LMP + Cycle Length – 14 days = Ovulation Date
- Fertile Window: Ovulation ± 5 Days
Example for a 31-Day Cycle:
You can simply use our calculator which is designed to accommodate different cycle length but here is an example for 31 days cycle when is ovulation
- LMP Start Date: 1st of the Month
- Cycle Length: 31 Days
- Ovulation Date: Day 17 (1st + 31 – 14 = 17th of the Month)
- Fertile Window: Days 12–18
- Next Period Start: 2nd of the Next Month (1st + 31 Days)
For irregular cycles, tracking for 3–6 months helps determine an average length for more accurate predictions.
SEX VS PERIODS
Can Sex Affect Your Cycle? Is It Safe During Ovulation?
Sex itself doesn’t change cycle length, but hormonal shifts, lifestyle factors, and stress can. However, sperm can survive in the body for up to five days, meaning conception can happen even if sex occurs before ovulation.
Sex and Pregnancy Risks:
- During Ovulation: Highest chance of pregnancy (use protection if not planning).
- After Periods: Can still lead to pregnancy if ovulation occurs early.
- Before Periods: Lower risk, but not impossible.
If you’re not looking to conceive, consistent contraceptive use is crucial—even during “safe” days.
STRESS VS PERIODS
How Anxiety Affects Your Cycle
Chronic stress disrupts the hypothalamic-pituitary-ovarian (HPO) axis, causing irregular periods, missed ovulation, or heavy bleeding.
- Late or Missed Periods: High cortisol can delay ovulation.
- Short or Long Cycles: Stress can lengthen or shorten your cycle.
- Increased PMS Symptoms: Anxiety can worsen cramps, bloating, and mood swings.
Managing stress with yoga, exercise, mindfulness, and a balanced diet can help regulate cycles naturally.
FOOD VS PERIODS
Foods to Regularize Periods & Improve Fertility
Your diet plays a key role in hormonal balance and cycle regulation.
Best Foods for Regular Periods:
- Leafy Greens & Nuts – Provide iron & magnesium to balance hormones.
- Flaxseeds & Chia Seeds – Help regulate estrogen levels.
- Papaya & Pineapple – May promote uterine contractions.
Best Foods for Fertility:
- Avocados, Nuts, Olive Oil – Contain healthy fats that support ovulation.
- Eggs & Fatty Fish – High in omega-3s & vitamin D to boost fertility.
- Whole Grains & Lentils – Provide fiber & B vitamins for hormone balance.
A balanced diet rich in essential nutrients ensures better cycle regulation and improved reproductive health.

How to Boost Your Chances of Conception
1. Track Ovulation & Identify Your Fertile Window
Timing is everything when it comes to conception. A woman’s fertile window is the time when an egg is released and available for fertilization. This window usually lasts for about 6 days—the five days leading up to ovulation and the day of ovulation itself.
How to Track Ovulation Accurately
✔ Calendar Method: Keep track of your menstrual cycle for at least 3–6 months to predict ovulation.
✔ Ovulation Predictor Kits (OPKs): These detect luteinizing hormone (LH) surges in urine, indicating ovulation is about to occur.
✔ Basal Body Temperature (BBT) Charting: Measure your temperature every morning before getting out of bed. A slight rise in BBT suggests ovulation has occurred.
✔ Cervical Mucus Changes: Before ovulation, cervical mucus becomes clear, stretchy, and slippery—similar to raw egg whites.
✔ Ovulation Pain (Mittelschmerz): Some women feel mild cramping on one side of the lower abdomen.
📌 Best Time for Conception: Have sex every 2–3 days from Day 10 to Day 18 of your cycle (if you have a 28–31 day cycle). This ensures sperm are present when ovulation happens.
2. Have Sex More Frequently – But Not Too Much
While timing intercourse during the fertile window is crucial, frequency also matters.
💡 Best Strategy for Conception:
- Every Other Day: Having sex every 2–3 days during your fertile window keeps sperm healthy and optimizes conception chances.
- Avoid Excessive Intercourse: Having sex multiple times a day may lower sperm quality and count.
- Don’t Stress Over Ovulation Day: Sperm can survive up to 5 days in the reproductive tract, meaning conception can occur even if sex happens before ovulation.
👉 Important: Avoid using lubricants that are not fertility-friendly, as some can reduce sperm motility.
3. Improve Sperm Health for Higher Fertility
Male fertility plays a 50% role in conception, so focusing on sperm health is just as important.
Tips to Increase Sperm Count & Motility
✔ Eat a Diet High in Antioxidants: Vitamin C, zinc, selenium, and omega-3s improve sperm quality.
✔ Maintain a Healthy Weight: Being overweight or underweight can affect sperm production.
✔ Avoid Excessive Heat Exposure: Hot tubs, saunas, and keeping laptops on the lap for long periods can harm sperm health.
✔ Reduce Alcohol & Caffeine Intake: Excessive alcohol and caffeine may lower sperm count.
✔ Quit Smoking & Avoid Drugs: Tobacco and recreational drugs negatively impact sperm motility.
📌 Sperm Quality Takes Time: It takes ~74 days for new sperm to develop, so lifestyle changes should be made at least 3 months before trying to conceive.
4. Eat a Fertility-Boosting Diet
Your diet plays a major role in hormonal balance, egg quality, and overall fertility. Nutrient-rich foods support healthy ovulation, implantation, and sperm function.
Best Foods to Improve Fertility
✔ Healthy Fats: Avocados, nuts, olive oil, and fatty fish help balance hormones.
✔ Leafy Greens & Vegetables: Spinach, kale, and broccoli are rich in iron and folic acid, essential for early pregnancy.
✔ Whole Grains & Fiber: Brown rice, quinoa, and oats help maintain stable blood sugar levels.
✔ Protein Sources: Eggs, chicken, lentils, and tofu provide essential amino acids for egg development.
✔ Dairy Products: Full-fat dairy (yogurt, cheese) may improve fertility compared to low-fat options.
✔ Fertility-Boosting Fruits: Oranges, berries, and bananas are rich in vitamins and antioxidants.
Foods to Avoid While Trying to Conceive
🚫 Processed & Sugary Foods: Can cause hormonal imbalances.
🚫 Excessive Caffeine: Keep under 200 mg per day (1-2 cups of coffee).
🚫 Trans Fats & Fried Foods: Linked to lower ovulation rates.
📌 Supplement Recommendation: Folic acid (400–800 mcg daily) is essential before and during early pregnancy.
5. Reduce Stress: The Hidden Fertility Blocker
High cortisol (stress hormone) levels can interfere with ovulation, making it harder to conceive. Stress can delay or stop ovulation altogether, leading to irregular cycles.
How to Reduce Stress Naturally
✔ Exercise Regularly: Gentle workouts like walking, yoga, and Pilates help regulate hormones.
✔ Try Meditation & Deep Breathing: Reduces anxiety and improves sleep quality.
✔ Get Enough Sleep: Poor sleep disrupts hormone regulation, affecting ovulation.
✔ Maintain a Work-Life Balance: Reduce overworking and prioritize relaxation.
📌 Fact: Studies show women undergoing fertility treatments who practice relaxation techniques are more likely to conceive than those who don’t.
6. Maintain a Healthy Weight (Neither Too Low Nor Too High)
Being overweight or underweight can disrupt ovulation and reduce conception chances. Find your BMI here
- Underweight (BMI <18.5): May cause irregular ovulation or missed periods.
- Overweight (BMI >30): Linked to hormonal imbalances and reduced egg quality.
💡 Ideal BMI for Fertility: Between 18.5 – 24.9 ensures optimal reproductive function.
7. Consider Seeing a Fertility Specialist If Needed
If you’ve been trying for over 12 months (or 6 months if over 35 years old) without success, consulting a doctor may help. A fertility specialist can evaluate hormone levels, ovulation patterns, and reproductive health.
Tests to Consider for Fertility Issues
✔ Hormone Testing (FSH, LH, AMH, Progesterone, Estrogen)
✔ Ultrasound to Check Ovulation & Uterus Health
✔ Semen Analysis for Sperm Count & Motility
✔ Fallopian Tube Blockage Tests (HSG Test)
If needed, options like medications (Clomid, Letrozole), IUI (Intrauterine Insemination), or IVF (In Vitro Fertilization) may be recommended.
BIRTH CONTROL
How to Prevent Pregnancy Naturally & With Contraceptives
If you’re not ready for pregnancy, combining methods ensures higher protection levels.
Birth Control Options:
✔ Hormonal Contraceptives: Pills, patches, IUDs, and implants prevent ovulation.
✔ Barrier Methods: Condoms and diaphragms physically block sperm.
✔ Withdrawal Method? Unreliable—pre-ejaculate can contain sperm.
✔ Tracking Ovulation: Helps avoid risky days, but not foolproof.
For emergency contraception, Plan B (Levonorgestrel) is effective within 72 hours after unprotected sex.
Luteal vs. Follicular Phase in Birth Control
The menstrual cycle consists of two key phases:
- Follicular Phase (Days 1–14):
- Starts from the first day of menstruation.
- Estrogen rises as the egg matures.
- Luteal Phase (Days 15–28):
- Begins after ovulation.
- Progesterone increases, preparing the body for potential pregnancy.
If progesterone levels are low, it can cause luteal phase defects, which affect conception and implantation.
