What is Pregnancy Week Tracking?

Pregnancy is measured in weeks from last menstrual period (LMP) — not from conception. Standard 40-week (280-day) gestation. Tracker shows: current week, day, trimester, days remaining, due date. Three trimesters: 1st (weeks 1-13), 2nd (14-27), 3rd (28-40). Each has unique developments and milestones.

How to use

  1. Choose input method — LMP date or due date
  2. Enter date — From doctor or self-tracked
  3. View week count — Plus trimester, days remaining
  4. Plan milestones — Scans, tests, baby shower

Tips

  • Important scans: Week 12 (NT scan), Week 20 (anatomy), Week 28 (glucose)
  • 2nd trimester (14-27): most comfortable; most travel happens here
  • 3rd trimester: prepare hospital bag, baby essentials
  • Track baby movements daily from week 28

FAQs

Why measured from LMP not conception?

LMP is more reliably known. Actual conception ~2 weeks later, but using LMP simplifies counting and is medical standard.

Due date accuracy?

Only ~5% of babies arrive exactly on due date. Normal range: 37-42 weeks. Earlier than 37 = preterm.

How is pregnancy detected?

Pregnancy test (urine or blood) 10+ days after expected period. Confirmed by doctor with HCG blood test and ultrasound.
