Diaphragm Fit Check: Bring Your Device Questions
Intimate HealthArticleWhat to ask at a fitting or use-check appointment, including changes since your last review.

In this article
If you notice a hole in a diaphragm or cap after sex, seek prompt advice from a pharmacist, sexual health clinic or clinician. You may need emergency contraception. Do not wait for a fitting appointment to raise that concern.1
Ask which device the appointment covers
Have the product name and model available when arranging the visit. Ask whether to bring your device, its packaging or its supplied instructions. Tell the clinic whether this is your first fitting, a follow-up check or a question about a device you already use.
The NHS1 describes a fitting in which a doctor or nurse examines inside the vagina to check the size. It also describes a demonstration and a later appointment to check correct use. Ask your own clinic what applies to your particular device.1
You can say: “This is the device I have. What will you check, and what should I bring?” Follow its supplied instructions and have the team clarify anything you do not understand.
Talk through the examination before it begins
The NHS1 says you can have a friend, family member or another staff member in the room for the fitting.1
If you would like someone present, tell the clinic when booking. Ask the clinician to explain what they plan to do before the examination starts. Bring up anything about the appointment that makes you hesitant, including a previous difficult examination.
You can ask: “Can you explain each part of the check before we begin?” If you need something clarified during the visit, say so.
Mention changes since the last check
NHS1 guidance says a different size may be needed after gaining or losing more than 3 kg, giving birth, or a miscarriage or abortion. It advises contacting a sexual health clinic or GP surgery about replacement and checking after childbirth before using the method again.1
Tell the team about a relevant change and when it happened. Ask whether your exact device needs review and what contraception plan to follow while that question is being settled. Let the clinician explain any change in size or restart instructions for your circumstances.
Leave with the use-check plan
Ask the team to show you which supplied instructions to follow and how any demonstration relates to your device. If another appointment is recommended, clarify its purpose and what you should bring.
Before leaving, ask who to contact if a question comes up at home. Keep that contact information with the instructions so you can describe the product clearly when asking for help.
