Every pregnant woman wants to know her due date. But a due date calculated from last menstrual period with a due date calculator often doesn’t match the due date that is estimated by ultrasound also known as a sonogram. During an ultrasound, a technician spreads a warm gel over the lower part of the abdomen, and then presses a tool called a transducer against the belly to examine the fetus using sound waves. An image of the fetus appears on an accompanying computer screen. While looking at this image, the technician takes some standard measurements from different angles and listens for a heartbeat. Sonograms are risk-free, and seeing your baby will likely be an enjoyable experience.
