The best time to perform a sonohysterogram is approximately a week after the start of your menstrual cycle. Please note, this procedure cannot be performed during your period, or if there is a possibility that you might be pregnant.
During the procedure, a thin catheter will be inserted through the opening of your cervix, placing the catheter inside the endometrial cavity. The catheter will be used to insert a small amount of sterile saline solution inside your endometrial cavity.
Following, ultrasound (an internal scan of your uterus) will be performed, via your vagina.
Thankfully, this procedure involves minimal discomfort, if any. For those who do experience pain, it is often described as “mild cramping” similar to menstrual discomfort. It is suggested that you take ibuprofen (with food) one hour prior to the procedure to minimize your discomfort.
