Tell your doctor if you are allergic to latex. A latex-free cover can be used for the ultrasound wand.
You may be asked to sign a consent form that says you understand the risks of the test and agree to have it done.
Talk to your doctor about any concerns you have about the need for the test, its
risks, how it will be done, or what the results will mean. To help you

How It Is Done
A sonohysterogram can be done in a doctor's office, a hospital, or a clinic. It usually takes about 15 to 30 minutes.
Your doctor may advise you to take an over-the-counter pain medicine before your appointment. This may help prevent cramping pain during the test.
Before a sonohysterogram, you empty your bladder. You then take off your clothes below the waist. You are given a gown or sheet to cover up with during the test.
For the test, you sit on the edge of a padded table. Then you lie back with your feet raised and supported by stirrups.
A sonohysterogram is done in several steps.
Transvaginal ultrasound. The tip of a thin ultrasound wand with gel on it is gently inserted into your vagina. You will need to lie very still while the ultrasound is being done.
A catheter is put in place. Next, your doctor inserts a smooth, curved tool called a speculum into your vagina. The speculum gently presses the vaginal walls outward, allowing your doctor to see the cervix. The cervix is washed. Then a flexible tube (catheter) is put in the cervix or through the cervix into the uterus.
Transvaginal ultrasound while the uterus is filled with fluid. The doctor then removes the speculum and reinserts the ultrasound wand. Onscreen, the ultrasound image shows the inside of your uterus while saline solution is injected through the tube into the uterus. Ultrasound images are taken and reviewed.
After the test, the ultrasound wand and then the tube are removed. Some of the saline solution flows through the fallopian tubes into your abdominal cavity. But most runs out of your cervix and vagina.
How It Feels
You probably will feel some cramping like
menstrual cramps from the fluid being injected into your uterus. After the test, you can expect a watery discharge for a few hours.
There is a small chance of pelvic infection after a sonohysterogram.
After the test
You may have cramping, spotting, or a watery discharge.
Call your doctor right away if you have:
A fever during the first 2 days after the test.
Vaginal discharge that changes or increases.
A sonohysterogram uses ultrasound to show the inside of the uterus.
