Understanding Your Pregnancy
How Pregnancy is Calculated
Pregnancy is calculated from the first day of your last menstrual period (LMP), not from conception. A full-term pregnancy lasts about 40 weeks (280 days) from the LMP. This method is used because the exact date of conception is often unknown.
The Three Trimesters
- First Trimester (Weeks 1-12): Major organs and structures form. Morning sickness is common. Risk of miscarriage is highest.
- Second Trimester (Weeks 13-26): Often called the "golden period." Energy returns, baby's movements felt, gender can be determined.
- Third Trimester (Weeks 27-40): Baby grows rapidly, gains weight. Prepare for labor and delivery. More frequent doctor visits.
Important Pregnancy Milestones
- Week 4-5: Positive pregnancy test possible
- Week 6-8: First ultrasound, heartbeat detected
- Week 12: End of first trimester, miscarriage risk decreases
- Week 18-20: Anatomy scan, gender reveal possible
- Week 20: Halfway point, baby movements felt
- Week 24: Viability milestone (baby could survive with medical care)
- Week 28: Third trimester begins
- Week 37: Full term, baby ready for birth
- Week 40: Due date

Frequently Asked Questions
How accurate is the due date?
The due date is an estimate. Only about 5% of babies are born on their exact due date. Most babies arrive within 2 weeks before or after the due date. Your doctor may adjust the date based on early ultrasound measurements.
When will I start showing?
First-time mothers typically start showing between 12-16 weeks. Women who've been pregnant before may show earlier. Body type, fitness level, and baby's position also affect when you show. Every pregnancy is different.
When can I find out the baby's gender?
Gender can typically be determined via ultrasound around 18-20 weeks during the anatomy scan. Some blood tests (NIPT) can determine gender as early as 10 weeks. Accuracy depends on baby's position and ultrasound quality.
What if my cycle is irregular?
If you have irregular cycles, the LMP method may be less accurate. Your doctor will likely use an early ultrasound (dating scan) to more accurately determine your due date based on the baby's size and development.
When will I feel the baby move?
First-time mothers typically feel movement (quickening) between 18-25 weeks. Women who've been pregnant before may feel it as early as 16 weeks. Early movements feel like flutters or bubbles. Movements become stronger and more frequent as pregnancy progresses.
What is considered full term?
Full term is 37-42 weeks. Early term is 37-38 weeks, full term is 39-40 weeks, late term is 41 weeks, and post-term is 42+ weeks. Babies born at 39-40 weeks have the best outcomes. Most doctors won't let pregnancy go beyond 42 weeks.
