Pregnancy Overview
What is Pregnancy? Pregnancy refers to the period (~9 months) during which one or more offspring develop inside a woman. Typically, childbirth occurs about 38 weeks after conception or roughly 40 weeks from the last menstrual period. According to the World Health Organization, a normal pregnancy term lasts between 37 and 42 weeks. While the estimated due date (EDD) is determined using a dating scan or the LMP, it’s important to remember that fewer than 4% of births occur exactly on the due date. Approximately 60% of births occur within a week of the EDD, and nearly 90% occur within two weeks of it.
Detecting Pregnancy: Pregnancy can be detected through tests or by observing symptoms, such as:
- Missed menstrual period
- Increased basal body temperature
- Fatigue
- Nausea
- Increased urination frequency
Tests include:
- Clinical Blood Tests: Detect hCG hormone as early as 6-8 days after fertilization and are highly accurate.
- Home Pregnancy Tests: Detect hCG in urine and are convenient, though slightly less sensitive than blood tests.
Managing Pregnancy
Medication: Medications taken during pregnancy can significantly affect fetal development. The FDA categorizes drugs from A (safe) to X (proven risk outweighs benefits). Pregnant individuals should always consult healthcare providers about any medication.
Weight Gain: Weight gain during pregnancy supports fetal growth and maternal health. The Institute of Medicine recommends:
- Underweight (BMI <18.5): Gain 28-40 pounds
- Normal weight (BMI 18.5-24.9): Gain 25-35 pounds
- Overweight (BMI 25-29.9): Gain 15-25 pounds
- Obese (BMI ≥30): Gain 11-20 pounds
Excessive or insufficient weight gain can increase risks like gestational hypertension and cesarean delivery.
Exercise: Aerobic and strength-conditioning exercises are typically safe for uncomplicated pregnancies and can:
- Improve physical fitness
- Decrease the risk of C-sections
However, caution is advised. Consult a doctor if experiencing symptoms like:
- Vaginal bleeding
- Dizziness or shortness of breath
- Decreased fetal movement
- Preterm labor
Nutrition: Nutritional needs increase during pregnancy. Key considerations include:
- Folic Acid (Vitamin B9): Reduces the risk of neural tube defects.
- DHA Omega-3: Essential for brain and retinal development.
A balanced diet with adequate vitamins, minerals, and hydration supports both maternal and fetal health. It is advisable to consult with a healthcare provider or dietitian to tailor nutritional plans.
