Frequently Asked Questions
How accurate is a pregnancy due date calculator?
Pregnancy due date calculators are generally accurate within 1-2 weeks. They use Naegele's Rule, which adds 280 days (40 weeks) to the first day of your last menstrual period. However, only about 5% of babies arrive exactly on their due date. Most babies are born between 37-42 weeks.
When should I start preparing my hospital bag?
It's recommended to have your hospital bag packed by week 36 of pregnancy. This ensures you're prepared in case of early labor. Include essentials for mom, baby, and your partner. Check our Hospital Bag Checklist section for a complete list.
What documents do I need for delivery?
Essential documents include: government-issued ID, insurance cards, medical records, prenatal test results, hospital registration forms, and your birth plan (if you have one). Keep copies of all important documents in your hospital bag.
How is my due date calculated?
Your due date is calculated by adding 280 days (40 weeks) to the first day of your last menstrual period (LMP). If your menstrual cycle is longer or shorter than 28 days, the calculator adjusts accordingly. Your healthcare provider may also adjust the date based on ultrasound measurements.
What are the three trimesters of pregnancy?
Pregnancy is divided into three trimesters: First trimester (weeks 1-13), Second trimester (weeks 14-27), and Third trimester (weeks 28-40). Each trimester brings different developmental milestones and physical changes.
