Cholestasis of pregnancy delivery timing depends on your bile acid results and the details of your pregnancy, so there is no single delivery week for everyone. Intrahepatic cholestasis of pregnancy (ICP) can affect when your care team recommends birth, and the timing should be planned with your obstetric team. [1][2] For more detail, see Cholestasis of Pregnancy: What It Is and What to Know.
That means two people with ICP may hear different recommendations; a date that fits one pregnancy may not fit another. Your care team can explain how your results and overall clinical picture shape the discussion, rather than relying on a week that applies to everyone. [1][2]
As you prepare for the conversation, focus on understanding the reason for the proposed timing and how it fits your care. For example, you can ask your obstetric team to explain why they recommend a particular week for your pregnancy and what the plan is based on. The goal is a plan you understand and can discuss with the people caring for you—not a date chosen by comparing your pregnancy with someone else’s.
Why bile acid results matter
Your bile acid result helps define the delivery window, but the recommended range is not a personal appointment date. For intrahepatic cholestasis of pregnancy (ICP) with total bile acid levels below 100 μmol/L, the Society for Maternal-Fetal Medicine (SMFM) recommends delivery between 36 0/7 and 39 0/7 weeks of gestation. [1]
That range leaves room for your care team to recommend different dates for different pregnancies. It does not mean you should expect to wait until 39 weeks, and it is not a promise that delivery will happen at the end of the window. Your clinician can explain where they recommend your plan fall within the range.
Put your latest result in context
Ask how your most recent bile acid result affects the date your team recommends. You might say, “With my latest result, what week are you recommending, and what makes that timing appropriate for me?” This keeps the conversation focused on what your number means for your plan, rather than on the range alone.
You can also ask whether any other details about your pregnancy affect the date. For example, if you receive a new test result before your next visit, ask whether it changes the recommendation or whether the existing plan still applies. Your care team can clarify what they are using to set the date and when they want to revisit it.
Leave the conversation with a clear date
Before you leave an appointment, make sure you understand the recommended week and the next step for confirming the delivery date. If the team gives you a range rather than one date, ask when they expect to choose a specific day and who will contact you. Writing down the answer can make it easier to keep track when you are managing several appointments or updates.
If you are unsure why your suggested date falls at one end of the window rather than another, ask directly. A useful question is, “What is the main reason for this timing in my situation?” The goal is to understand how your results and circumstances connect to the recommendation, not to assume that every pregnancy with ICP follows the same schedule.
What can shift the suggested delivery week
Clinicians do not use the same delivery week for every pregnancy with cholestasis; the suggested timing depends on which guidance they follow and how the condition is classified. A 2025 review summarizing FIGO guidance describes different gestational-age windows by severity, including 35–36 weeks for severe disease. [3] To go further, see Cholestasis of Pregnancy Diagnosis: Tests and Follow-Up.
That range is not a schedule to apply to every diagnosis. It shows why two people with cholestasis may hear different suggested weeks, even when both are discussing planned delivery. Your clinician can explain how your specific circumstances fit the approach they recommend.
Guidance from different organizations should not be blended into one universal calendar. For example, the FIGO windows summarized in the review are distinct from the SMFM recommendation for patients with total bile acid levels below 100 μmol/L, which gives a window of 36 0/7 to 39 0/7 weeks. [3][1] These recommendations are framed for different groups and should not be read as interchangeable.
When you discuss a suggested week, ask which guidance your care team is using and why it fits your pregnancy. You might say, “Are you applying FIGO or SMFM guidance in my case?” and “What makes this week the right fit for me?” That helps you understand the reasoning without comparing your plan with someone else’s.
If the recommendation changes during follow-up, ask what new information led to the change and what the next step is. You can also ask your clinician to explain the plan in plain language, including what timing they recommend and when you should check back. The goal is a clear plan that reflects your care team’s approach to your pregnancy, not a week chosen simply because it appears in a general guideline.
Questions to bring to your care team
Bring a short list of questions to your care team so you leave with a clear delivery plan and know what to do if circumstances change. You can write the answers in your phone or ask someone you trust to come with you.
Ask how your result connects to the plan
Ask, “What does my total bile acid result mean for the delivery window you recommend?” If you have more than one result, ask which result the team is using and how it affects the date they suggest. SMFM recommends delivery between 36 0/7 and 39 0/7 weeks for ICP with total bile acid levels below 100 μmol/L. [1]
You can also ask what would make the team recommend the earlier or later part of the window in your situation. For example: “What is the reason for the week you’re recommending, and what would lead you to revisit it?” This helps you understand the plan without assuming that a general recommendation gives you a specific date.
Check whether the plan could change
Ask whether you should have repeat testing and when to expect the next update. You might say, “If my next result is different, would that change the delivery plan?” Also ask whether a change in symptoms should prompt a call or a review of the plan.
Before you leave, confirm who will contact you with results and how to reach the team if you have a question between appointments. If no repeat test is planned, ask whom to contact if your symptoms change. These are practical questions to clarify together; your team can tell you what applies to your care.
Make a plan for labor or a change in symptoms
Ask, “If labor starts before the planned date, where should I go and whom should I call?” Confirm the after-hours number and whether you should call before traveling to the hospital. You can also ask what symptoms or other changes should prompt a call, and whether any changes mean you should call right away.
Before the appointment ends, repeat the plan in your own words: the expected delivery window, what follow-up is next, and what to do if labor begins early or something changes. If any part is unclear, ask for it to be explained again or written down.
Common questions about delivery timing
Is delivery always planned at 36 weeks?
No. For pregnancies with intrahepatic cholestasis and total bile acid levels below 100 μmol/L, the Society for Maternal-Fetal Medicine (SMFM) recommends delivery within a range from 36 0/7 to 39 0/7 weeks. [1] That range means a plan may fall at different points within the window; it does not make 36 weeks the automatic date for everyone.
For example, two people with results below that threshold may still discuss different dates with their care teams. If you hear “36 weeks,” ask whether that is the recommendation for your specific pregnancy or one option within the broader range.
Does one bile acid threshold determine every plan?
No single lab value should be treated as a complete birth plan. Your care team interprets your results in the context of your pregnancy, so a threshold alone does not tell you which date will be recommended.
You can ask how the team is using your results to choose a date. For instance, if a result is close to a threshold, ask what that means for the timing discussion rather than assuming the number gives you a fixed answer.
Can you choose the delivery date yourself?
You can share your preferences and ask about the options, but delivery timing is a clinical decision to discuss with your care team—not a one-size-fits-all rule. The recommendation may not match the date you would pick on your own, so ask the team to explain its reasoning and how much flexibility there is.
It can help to bring a practical preference, such as wanting time to arrange childcare or support, and ask whether it can fit with the recommended plan. If the proposed date feels unclear or difficult, say so and ask what alternatives the team considers appropriate for your pregnancy.
Make a clear, individualized birth plan
Your birth plan should reflect your bile acid results and the full clinical picture, not a date chosen by comparing pregnancies. [1] Before you leave an appointment, ask your care team to confirm the recommended week, why it fits your situation, and what happens next. [1]
Try to leave with a plan you can explain in plain language: “We’re aiming for this week because of my results and circumstances, and this is what I should do if anything changes.” If the recommendation feels unclear, ask the clinician to walk through how they arrived at it and what would prompt another discussion. Your plan may feel different from a friend’s or family member’s, but another person’s date does not tell you what is right for your pregnancy.
You can also make the next step concrete. For example, ask when your team wants to speak with you again, who to contact with questions, and how you will hear about any change to the plan. Write down the recommended week and the reason for it, or ask your support person to take notes if that makes the conversation easier.
The main takeaway is that delivery timing is a shared, individualized plan—not a date to copy from someone else. Confirm the recommended week, the reason behind it, and your next steps directly with your pregnancy care team.
