Understanding Your Pregnancy Timeline
Pregnancy is typically 40 weeks long, counted from the first day of your last menstrual period (LMP). However, most babies are born between 37 and 42 weeks.
Pregnancy Trimesters Breakdown:
- First Trimester (Weeks 1-12):
- Early pregnancy symptoms like nausea, fatigue, and hormonal changes occur.
- The baby’s heart, brain, spinal cord, and organs begin to form.
- By Week 6, the baby’s heartbeat can be detected by ultrasound.
- By Week 12, the risk of miscarriage decreases.
- Second Trimester (Weeks 13-26):
- You may feel more energetic as morning sickness fades.
- Baby starts making noticeable movements, and gender can be determined around Week 18.
- The baby starts to hear sounds and respond to stimuli.
- At Week 23, a premature baby may have a chance of survival with medical care.
- Third Trimester (Weeks 27-40):
- Baby grows rapidly, gains fat for warmth, and develops lungs.
- By Week 28, the baby can breathe on its own.
- By Week 38, the baby is full-term and ready for birth.
- Labor can happen naturally anytime between Weeks 37-42.
How is the Due Date Calculated?
The Estimated Due Date (EDD) is determined by adding 280 days (40 weeks) to the first day of your Last Menstrual Period (LMP). This method assumes a 28-day menstrual cycle, but actual due dates can vary.
👉 Example Calculation:
- If your LMP was September 19, 2024, your estimated due date would be June 25, 2025.
- Your pregnancy would be divided into three trimesters, and key milestones would be marked along the way.
📝 Note: The due date is only an estimate! Only 5% of babies are born exactly on their due date. Most births occur within a two-week window before or after the EDD.

Frequently Asked Questions (FAQs)
1. Is the due date 100% accurate?
No, the due date is an estimate. Babies are often born between Weeks 37-42, not exactly on the due date.
2. How do I know my pregnancy week?
Your pregnancy week is counted from the first day of your last period (not from conception). The calculator helps determine your exact week.
3. What if I don’t remember my LMP?
If unsure, an ultrasound scan can estimate your due date based on baby’s growth.
4. Can this calculator be used for twin pregnancies?
Twin pregnancies may have different growth rates and due dates. Always consult your doctor for twin or multiple pregnancies.
