Pregnancy Overview

Pregnancy is the term describing the development of one or more offspring inside a woman, typically lasting ~40 weeks from the last menstrual period or ~38 weeks from conception. The World Health Organization considers a normal pregnancy term to last between 37 and 42 weeks.

How Pregnancy is Calculated

  1. Due Date: Based on the estimated date provided by your healthcare provider or an ultrasound.
  2. Last Menstrual Period (LMP): Pregnancy is calculated from the first day of your last period.
  3. Conception Date: The due date is calculated by adding 266 days to the conception date.
  4. IVF Transfer Date: When using IVF, the timeline is estimated based on the embryo transfer date and embryo age (3-day or 5-day).

Pregnancy Management Tips

  1. Weight Gain: Recommended weight gain depends on your BMI and is essential for a healthy pregnancy. Consult with your doctor or use the Pregnancy Weight Gain Calculator for guidance.
  2. Exercise: Moderate aerobic and strength-conditioning exercises are usually recommended during pregnancy. Consult your doctor for tailored advice.
  3. Nutrition: A balanced diet rich in essential nutrients, including folic acid and DHA omega-3, supports fetal development. Consult a dietitian or healthcare provider for personalized recommendations.

Note: Every pregnancy is unique. For the most accurate guidance, consult your healthcare provider.
