The frequency of the scans depends on your pregnancy's progress and any risk factors. Typically, it is performed every 4 weeks in uncomplicated cases, but more frequent scans may be necessary if there are concerns about growth or blood flow.

Yes, Doppler ultrasound is a safe, non-invasive procedure. It uses sound waves, not radiation, and is widely used in prenatal care to monitor blood flow without harming the fetuses.

While the scan can provide important insights into the health and growth of the fetuses, it cannot directly predict preterm labor. However, abnormal findings, such as poor blood flow or unequal growth, may indicate a higher risk, allowing for closer monitoring and preventive care.

If the scan detects problems such as IUGR, TTTS, or placental insufficiency, your healthcare provider may recommend additional tests, increased monitoring, or specific treatments to manage the condition and reduce risks.
