hCG, Early Tests & First Ultrasound

Early pregnancy diagnostic approach

Early pregnancy diagnostic approach

Why early pregnancy diagnosis is stepwise Early pregnancy can be difficult to diagnose because normal symptoms overlap with premenstrual changes, gastrointestinal illness, stress, and irregular cycles. Even in a medically supervised setting, the first evaluation rarely answers everything at once. A stepwise approach reduces the risk of missing an ectopic pregnancy or misclassifying a very […]

Falling hCG levels and when to repeat testing

Falling hCG levels and when to repeat testing

What a falling hCG level can mean In a typical early pregnancy, hCG rises rapidly after implantation. Because of that expected pattern, a falling hCG result often signals that the pregnancy is not developing in the usual way. In the first 8 to 10 weeks, a slow rise or a drop may reflect trophoblastic tissue […]

Anatomy scan (20-week ultrasound)

Anatomy scan (20-week ultrasound)

What is the anatomy scan? The anatomy scan is a structured ultrasound examination performed in the second trimester to evaluate fetal anatomy and growth. It is commonly called the 20-week ultrasound because it often takes place near the halfway point of a 40-week pregnancy, though the usual window is approximately 18 to 22 weeks. Unlike […]

Ultrasound types and first trimester ultrasound purpose

How pregnancy ultrasound works Ultrasound imaging uses sound waves emitted from a transducer. These waves travel through tissue and return as echoes that are converted into images on a screen. In pregnancy, ultrasound can show fluid-filled spaces such as the gestational sac, soft-tissue structures such as the uterus and ovaries, and, later in the first […]

Normal hCG levels and slow rising hCG explained

Normal hCG levels and slow rising hCG explained

What hCG is and why it rises in early pregnancy hCG is produced by trophoblastic tissue, which later contributes to the placenta. After implantation, hCG enters the bloodstream and then the urine, which is why it can be detected by both quantitative blood tests and home urine pregnancy tests. One of hCG’s key early roles […]

Pregnancy blood test (hCG) and quantitative hCG explained

Pregnancy blood test (hCG) and quantitative hCG explained

What is hCG? Human chorionic gonadotropin is a glycoprotein hormone produced primarily by placental trophoblast cells after implantation. Its early role is to support the corpus luteum, which helps maintain progesterone production until the placenta becomes more hormonally self-sufficient. In practical terms, hCG is the hormone detected by pregnancy tests. It enters the bloodstream first […]
