Revision Question 2
Feedback
B. The uterus is retroverted (tilted backwards). Note that the bladder is filled but the uterus bends towards the back. In this situation, an early pregnancy would be difficult to see because the top (fundus of the uterus), where the embryo implants, is a long way from the probe.
When the uterus is retroverted, it is more difficult to see even if the bladder is full. A normal pregnancy will implant in the fundus and if the uterus is retroverted, as shown in the image below, this will be difficult to see.
The image below shows an anteverted uterus. The fundus is closer to the probe. Remember – an anteverted uterus is one that tilts forward towards the anterior wall of the abdomen.
