The first ultrasound in an IVF pregnancy is extremely important because it provides critical early information about the success and progress of the pregnancy. Here’s why:

1. Confirms Pregnancy Location
- Ensures the embryo is implanted inside the uterus, not in the fallopian tubes (which would indicate an ectopic pregnancy, a medical emergency).
👶 2. Detects Fetal Heartbeat
- Typically done around 6-7 weeks of gestation, it checks for the presence of a fetal heartbeat, confirming a viable pregnancy.
📊 3. Checks Gestational Sac & Yolk Sac
- Helps in confirming the presence and size of the gestational sac and yolk sac, which are early indicators of a healthy pregnancy.
🔢 4. Determines Number of Embryos
- Tells whether it is a singleton or multiple pregnancy (twins, triplets, etc.), which is common in IVF cases.
📏 5. Estimates Accurate Due Date
- Early measurement of the crown-rump length (CRL) helps calculate a more accurate due date than later ultrasounds.
🚨 6. Rules Out Early Complications
- Detects any early signs of miscarriage, blighted ovum, or subchorionic bleeding, allowing timely management.
