Planning to conceive? Use these calculators to optimize your fertility journey:
📅 Track Your Cycle
Use the menstrual cycle calculator to understand your cycle patterns. Record at least 3-6 months of cycle data to identify your average cycle length and ovulation patterns.
🥚 Identify Ovulation
The ovulation calculator predicts when you'll ovulate based on your cycle. Most pregnancies occur from intercourse 1-2 days before ovulation through ovulation day.
💕 Plan Intercourse
Use your fertile window (6 days: 5 before ovulation + ovulation day) to plan intercourse for conception. Daily intercourse or every-other-day intercourse during this window maximizes pregnancy chances.
⏱️ Health Optimization
Before conception, optimize nutrition, manage stress, maintain healthy weight, exercise regularly, and stop smoking. Preconception health care improves pregnancy outcomes.
🤰 Pregnancy Tracking
Once pregnant, use these tools to monitor your progress and health:
📅 Due Date Calculation
Calculate your estimated due date using LMP, ultrasound, conception, or IVF transfer date. Note that only about 5% of babies arrive exactly on the due date.
🤰 Pregnancy Timeline
Track which trimester you're in, key development milestones, and what to expect each week. Understand major changes in your body and baby's development.
⚖️ Weight Gain Monitoring
Track recommended weight gain based on your pre-pregnancy BMI. Appropriate weight gain supports healthy fetal development and reduces pregnancy complications.
✨ Conception Dating
Calculate when conception likely occurred based on your due date. Important for paternity and pregnancy verification, especially in medical records.
📊 Prenatal Care Timeline
Typical prenatal care schedule and important milestones:
First Trimester (Weeks 1-12)
Initial prenatal visit with medical history, blood tests, dating ultrasound, and risk screening. Monthly visits. Many announce pregnancy after week 12 when miscarriage risk drops.
Early Second Trimester (Weeks 13-16)
Sequential screening tests optional. Monthly prenatal visits continue. Energy typically returns, and morning sickness often resolves. Fetal movement may be felt toward end of period.
Mid-Second Trimester (Weeks 17-20)
Anatomy scan (detailed ultrasound checking all organs). Fetal sex often determined. Growth and development verified. Monthly visits continue.
Late Second Trimester (Weeks 21-26)
Glucose tolerance test around week 24 for gestational diabetes screening. More frequent fetal movement. Monthly prenatal visits.
Early Third Trimester (Weeks 27-30)
Viability point (baby can survive with medical care if born). Visits increase to every 2 weeks. Blood pressure and weight monitored. Rh antibody screening if needed.
Mid-Late Third Trimester (Weeks 31-35)
Baby positioning checked. Growth monitored. Visits every 2 weeks. Discussion of labor, delivery options, and final preparations.
Final Trimester (Weeks 36-40)
Visits increase to weekly. Labor signs discussed. Fetal position confirmed. Group B Strep testing. Final preparations for delivery. Labor induction typically offered by week 42.
🏥 Prenatal Care Essentials
Key Components of Prenatal Care
Regular Check-ups: Scheduled appointments to monitor mother's health and baby's development. Blood Tests: Screen for anemia, infections, gestational diabetes, and genetic conditions. Ultrasounds: Visualize baby, confirm dating, check development, and detect abnormalities. Blood Pressure Monitoring: Check for preeclampsia and hypertension.
Important Prenatal Tests
Dating Ultrasound (8-14 weeks): Confirms pregnancy dating, viability, and number of babies. First Trimester Screening (11-14 weeks): Optional blood tests and ultrasound to assess chromosomal abnormality risk. Anatomy Scan (18-22 weeks): Detailed ultrasound checking all fetal structures and development. Glucose Tolerance Test (24-28 weeks): Screens for gestational diabetes.
Nutrition During Pregnancy
Prenatal Vitamins: Take prenatal vitamins containing folic acid (400-800 mcg) to prevent neural tube defects. Adequate Calories: Add 300-500 calories per day in second and third trimesters for appropriate weight gain. Protein: Aim for 70-100 grams daily for fetal development. Safe Foods: Avoid raw/undercooked meats, unpasteurized dairy, high-mercury fish, and deli meats.
Lifestyle During Pregnancy
Exercise: 150 minutes of moderate activity weekly if previously active. Walking, swimming, and prenatal yoga are ideal. Sleep: Aim for 7-9 hours nightly; left-side sleeping improves circulation. Stress Management: Practice relaxation techniques, meditation, or prenatal counseling. Avoid Harmful Substances: No smoking, alcohol, or recreational drugs.
