The 4th week of pregnancy is a significant milestone in your journey to motherhood. Congratulations on reaching this stage! Your body is already undergoing major changes to support the developing embryo. This is the time when the embryo implants itself into the uterine lining, marking the official beginning of pregnancy. Monitoring hCG levels in week 4 is crucial, as it helps track pregnancy progress and ensures everything is developing as expected.
What is Beta-hCG and Its Role in Early Pregnancy?
Beta-human chorionic gonadotropin (beta-hCG) is a hormone produced by the placenta shortly after the embryo implants. It is commonly known as the pregnancy hormone because its presence confirms pregnancy. hCG levels are typically measured through blood and urine tests to track pregnancy progression.
During the 4th week of pregnancy, hCG levels can vary significantly among individuals. The normal range of hCG levels in week 4 is between 5 and 426 mIU/mL. Rising hCG levels indicate a healthy pregnancy, with levels doubling approximately every 48 to 72 hours.
Beta-hCG Levels at Different Pregnancy Stages
hCG level at 3 weeks pregnant: Usually between 5-50 mIU/mL
hCG level at 4 weeks pregnant: Ranges from 5-426 mIU/mL
hCG level 5 weeks pregnant: By the 5th week, hCG levels range from 18 to 7,340 mIU/mL
hCG levels at 6 weeks pregnant: Typically between 1,080-56,500 mIU/mL
If hCG levels plateau or drop, it may indicate a potential concern such as a miscarriage or ectopic pregnancy. In such cases, further testing and medical evaluation are necessary.

Symptoms at 4 Weeks Pregnant
At 4 weeks, you may start noticing early pregnancy symptoms, including:
Mild Cramping: Due to embryo implantation, similar to period cramps.
Spotting: Known as implantation bleeding, lighter than a regular period.
Breast Tenderness: Hormonal changes cause swelling and soreness.
Fatigue: Increased energy demands can lead to exhaustion.
Mood Swings: Hormonal shifts may cause emotional fluctuations.
Frequent Urination: Rising hCG levels increase kidney activity.
Negative Signs After Embryo Transfer & Pregnancy Concerns
For those who have undergone IVF embryo transfer, monitoring symptoms is essential. Negative signs after embryo transfer include severe cramping, heavy bleeding, or a drop in hCG levels. If you experience any of these, contact your doctor immediately.
Essential Tips for the 4th Week of Pregnancy
Take a Home Pregnancy Test: Choose a test with high sensitivity for detecting beta-hCG levels.
Schedule a Prenatal Visit: Confirm your pregnancy and start prenatal care.
Start Prenatal Vitamins: Folic acid, iron, and calcium are essential for fetal development.

Variation in Beta-hCG Levels
Each pregnancy is unique, and hCG levels can vary due to factors like:
Singleton vs. Twin Pregnancy: Twin pregnancies often have higher hCG levels.
Medical Conditions: Thyroid disorders or medications may affect hCG levels.
Health Complications: A sudden drop in hCG levels may indicate pregnancy concerns.
