A SONOHYSTEROGRAM is a procedure during which a catheter is placed through the cervix and normal saline is injected into the uterus during an ultrasound. This procedure, performed by a physician, outlines the interior contour of the uterus to determines if any structural abnormalities of the uterine cavity exist.
The sonohysterogram should be done within a few days after your menstrual periods ends. At that time the uterine lining is thin and it would be unlikely you may be ovulating or early pregnant when the examination is performed.
