If your doctor has recommended an HSG test, it is natural to have questions: Which cycle day should you book? Can you come alone? What medicines should you take? A little planning can make the visit easier and help avoid an appointment being postponed.
HSG Test Preparation starts with confirming your cycle dates and receiving the diagnostic centre’s instructions. This guide from Nisarga Diagnostics, Sanjaynagar, Bengaluru, explains what to check before your visit, what to bring and which questions to ask.
- Record the first day of your period and confirm your test date with the clinic.
- Arrange someone to accompany you if possible.
- Allow time for registration, the procedure and recovery before travelling.
- Wear comfortable, preferably dark-coloured clothing and carry a sanitary pad.
- Take antibiotics, pain relief or other medicines only as instructed.
What is an HSG test, and why is it recommended?
HSG stands for hysterosalpingography. It is an X-ray examination using contrast fluid to show the inside of the uterus and whether the fallopian tubes are open. It may be recommended as part of fertility investigations.
The result answers a specific question about the uterine cavity and tubes. It does not replace the full fertility assessment. Ask your referring gynaecologist what information they want from the test and how they will discuss the report with you.
HSG Test Preparation: count your cycle days carefully
The first day of menstrual bleeding is Day 1. HSG is usually scheduled after bleeding has stopped and before ovulation, in the first half of the cycle. Many centres use a window around days 7–10, but the exact date depends on your cycle and the clinic’s protocol.
Confirm the date before you travel
Write down when your period started and give that date to the booking team. For example, if bleeding begins on the 3rd, that is Day 1; the 4th is Day 2. Do not start counting from the last day of bleeding.
If your period arrives earlier or later than expected, call the clinic to recheck the booking. Mention irregular cycles, ongoing bleeding or uncertainty about your dates. A quick confirmation can save an unnecessary journey.
Tell the team about pregnancy possibility, infection and allergies
HSG should not be performed during pregnancy or an active pelvic infection. Inform the clinic if pregnancy is possible, if you have symptoms of infection, or if you have previously reacted to iodinated X-ray contrast. Share your current medicines and relevant medical history.
Ask what precautions to follow regarding sexual intercourse before the appointment and whether a pregnancy test is required. Do not assume that being early in your cycle is sufficient on its own. Follow the centre’s specific instructions.
Bring someone and leave enough time for your visit
Plan a comfortable journey home
An accompanying family member or trusted friend can help with travel and support if you feel tired or unwell. Check the centre’s companion policy: they may be able to wait nearby even if they cannot enter the examination room.
Avoid placing a tightly scheduled work meeting or long journey immediately after the appointment. Ask the booking team how much time to allow for check-in, discussion, the test and any observation afterwards. The total visit may take longer than the examination itself.
Clothing, documents and practical items to bring
Dark-coloured clothing is a practical choice because light spotting may occur, but it is not a medical requirement. Comfort matters: you may be asked to change into a gown. Carry a sanitary pad or panty liner for afterwards.
- Your doctor’s prescription or referral.
- The start date of your most recent menstrual period.
- Relevant ultrasound reports and fertility investigation records.
- A list of your medicines and any known allergies.
- Identification and any other documents requested by the centre.
- The clinic’s written preparation instructions, if provided.
Keep the records together in one folder. If a previous report is on your phone, check that you can open it before leaving home. Confirm which documents the clinic needs rather than assuming every centre has identical requirements.
Medicines are an important part of HSG Test Preparation
Your doctor may prescribe antibiotics or recommend pain relief, depending on your circumstances. Ask for clear instructions about the medicine name, timing and duration. Do not start antibiotics independently or change a prescribed course without advice.
Ask these questions before the appointment
“Should I take any medicine before arriving?” “At what time?” “Do I need to continue it afterwards?” “What should I do if I miss a dose?” These questions are more useful than copying another patient’s medication schedule.
Also confirm whether you can eat and drink normally and whether you should take your regular medicines. Tell the team about drug allergies and any condition that affects which pain medicines you can use. If sedation is planned, request the specific fasting and transport instructions.
What happens during an HSG test?
The team explains the procedure and obtains your consent. During the examination, a speculum is used to view the cervix, and a thin tube is positioned to introduce contrast into the uterus. X-ray images show how the contrast travels through the uterine cavity and tubes.
You may feel cramping as the fluid is introduced. Tell the team how you are feeling and ask questions if anything is unclear. Discuss pain relief before the visit rather than waiting until the procedure starts.
After HSG: what to watch for
Mild cramps, light spotting or some discharge may occur afterwards. Use a sanitary pad rather than a tampon and follow your written aftercare advice. Ask when you can return to work, exercise and sexual activity, and how you will receive your results.
Contact a doctor promptly for fever, chills, heavy bleeding, foul-smelling discharge, fainting or severe or worsening abdominal pain. Seek urgent help for breathing difficulty or signs of a serious allergic reaction. Do not dismiss these symptoms as routine recovery.

Frequently asked questions about HSG Test Preparation
How do I count Day 1 for HSG?
Count the first day of menstrual bleeding as Day 1, rather than the day your period finishes. If you have only spotting or an unusual cycle, describe this to the clinic and ask how to count your appointment date.
Can I have HSG on any day of the month?
No. The appointment needs to fit your menstrual cycle and the clinic’s pregnancy-exclusion protocol. Confirm the permitted dates before travelling to the centre.
What if my periods are irregular?
Tell your gynaecologist and the diagnostic centre when booking. Do not estimate a suitable day from a friend’s experience; your team may need a different scheduling plan.
Should I come if I am still bleeding?
Call the clinic first. HSG is generally arranged after menstrual bleeding has stopped, before ovulation. The team should decide whether your appointment needs to be changed.
Is HSG the same as an internal ultrasound?
No. HSG uses X-rays and contrast to assess the uterine cavity and fallopian tubes. An internal ultrasound uses sound waves and answers different clinical questions.
Do I need antibiotics for every HSG test?
Not everyone receives the same prescription. Follow your doctor’s instructions and ask when to start and finish any prescribed medicine. Do not take leftover antibiotics or copy someone else’s prescription.
Will the HSG test hurt?
Some people experience period-like cramps or discomfort. Discuss pain relief beforehand so you know what is appropriate for you. Tell the team if you feel unwell during the procedure.
Do I need someone to accompany me?
Having a trusted person available can help if you feel tired, dizzy or uncomfortable afterwards. Ask whether they may wait at the centre and arrange your journey home.
What should I wear and bring?
Choose comfortable clothing; dark colours may be more practical if spotting occurs. Bring a sanitary pad, your prescription, relevant reports, medicine list and the date your last period started.
Do I need to fast or drink extra water?
Ask the clinic for its HSG-specific instructions. Do not automatically follow the preparation for an abdominal ultrasound or TVS. Confirm food, fluids and medicines, particularly if sedation is planned.
Is light spotting after HSG expected?
Light spotting or discharge can occur. Use a pad and follow the aftercare instructions. Heavy bleeding, fever or severe or worsening pain needs prompt medical assessment.
When can I resume sex or try for pregnancy?
Follow the instructions from your treating doctor and the centre. Advice may vary with the procedure, symptoms and treatment plan; ask before leaving rather than assuming a universal waiting period.
Does an HSG result explain every cause of infertility?
No. It provides information about the uterine cavity and tubal openness. Your gynaecologist will interpret it alongside your history and other fertility investigations.
Can HSG be done if I might be pregnant?
Tell the team immediately if pregnancy is possible, even if your appointment date appears correct. HSG should not be performed during pregnancy; the clinic may require a pregnancy test.
