Everything you need to know about HCG levels during pregnancy

Week 4-5: The Early Signs

In the early stages of pregnancy, around weeks 4-5, hCG levels start to rise rapidly. At this stage, you may experience early pregnancy symptoms such as fatigue, tender breasts, and increased urination. HCG levels typically range between 5 and 426 mIU/ml during these weeks.

Week 6-8: Ultrasound and Heartbeats

Between week 6 and 8, hCG levels become more reliable as an indication of pregnancy progression. You can now plan for your first ultrasound to confirm that everything is on track. HCG levels should be somewhere between 1080 and 229,000 mIU/ml during these weeks.

Week 9-12: Stabilization

As you enter the second trimester, hCG levels will stabilize. They decrease slightly and usually range between 25,700 and 288,000 mIU/ml. Your symptoms may also begin to ease as your body adjusts to pregnancy.

Week 13-16: Entering the Second Trimester

HCG levels continue to decline, and during this phase, they usually range between 13,300 and 254,000 mIU/ml. You are now entering the second trimester and might begin to feel the first movements of your little one.

Week 17-20: Midpoint and Ultrasound

Around weeks 17-20, you will undergo a routine ultrasound to check your baby's development. HCG levels continue to drop and are typically between 4,060 and 165,400 mIU/ml on average.

Week 21-40: The Home Stretch

During the latter half of pregnancy, hCG levels will decrease further, ranging between 3,640 and 117,000 mIU/ml. You will soon meet your little one, and preparations for childbirth are in full swing.

Understanding the changes in HCG levels during pregnancy can provide valuable information about your baby's development and health. Remember that every pregnancy is unique, and your HCG levels may vary. If you have any uncertainty or questions about your HCG levels, don't hesitate to contact your midwife or doctor.
