How to use it
- Choose United States (ACOG/CDC) or United Kingdom (NHS).
- Enter your due date, or the first day of your last period.
- Review the list: past items are checked off and current ones say due now.
- Download the schedule to your calendar with the .ics button.
How the schedule works
Pick your country, then enter your due date (best, if your provider has given you one) or the first day of your last period. The tool works out how far along you are today and lists every item in week order with its window and the matching dates on your calendar.
Each item is tagged as a visit, test or vaccine. Items whose window has passed are checked off and faded, and anything in its window right now is marked due now. The .ics button saves all of it as a calendar file for Google Calendar, Apple Calendar or Outlook. Sources are linked under the list.
The last-period option assumes a 28-day cycle. If yours is different, or an ultrasound changed your dates, enter the due date instead; the due date calculator can help. Everything runs in your browser and nothing is saved.
How often are prenatal visits in the US?
The Office on Women's Health (HHS) describes the typical schedule for a healthy pregnancy:
- Weeks 4 to 28: about once a month
- Weeks 28 to 36: twice a month
- Week 36 to birth: every week
The schedule places the first visit at 6 to 10 weeks. It is usually the longest one: health history, a physical exam and first-trimester blood work. If you have a chronic condition, are carrying twins or develop a complication, your provider may see you more often or order extra tests.
US tests and vaccines by week
| Weeks | Test or vaccine | Notes |
|---|---|---|
| 6–13 | First-trimester labs | Blood type and Rh, antibody screen, blood count, infections including syphilis |
| 10–13 | First-trimester screening (optional) | Blood test plus nuchal translucency ultrasound |
| from 10 | Cell-free DNA screening (NIPT, optional) | Results in about a week; a positive screen needs a diagnostic test |
| 15–22 | Quad screen (optional) | Blood test |
| 18–22 | Anatomy ultrasound | Detailed check of the baby |
| 24–28 | Glucose screening | Earlier if you have risk factors |
| 27–36 | Tdap (whooping cough) | Every pregnancy, preferably early in the window |
| 28 | Rh immune globulin | Only if you're Rh negative; again within 72 hours of birth if the baby is Rh positive |
| 32–36 | RSV vaccine | Seasonal; or your baby gets an RSV antibody shot after birth |
| any week | Flu shot | During flu season |
| 36–37 | Group B strep (GBS) swab | ACOG: 36 0/7 to 37 6/7 weeks |
ACOG also recommends syphilis testing three times: at the first visit, in the third trimester and at delivery. The Office on Women's Health lists glucose screening at 26–28 weeks, slightly later than ACOG's 24–28. For RSV, CDC's consumer page lists September through January, while ACOG's 2026–27 guidance extends the window to September 1 through March 1. Ask your provider which applies to you.
Worked example: due date 07/04/2027
A due date of 07/04/2027 means your LMP-equivalent date is 09/27/2026. The schedule then shows:
- Anatomy ultrasound (18–22 weeks): 01/31/2027 to 03/06/2027
- Glucose screening (24–28 weeks): 03/14/2027 to 04/17/2027
- Tdap (27–36 weeks): 04/04/2027 to 06/12/2027
- GBS swab (36–37 weeks): 06/06/2027 to 06/19/2027
The RSV window (32–36 weeks) would fall in May and June 2027, outside both the CDC and ACOG seasons. The tool lists the week window but doesn't check the season, so in a case like this, ask your provider about the RSV antibody shot for your baby instead.
The UK (NHS) schedule
Choose United Kingdom (NHS) to see the NHS antenatal pattern. For a first baby, the NHS offers at least 10 appointments (at least 7 if you've given birth before) and two scans:
- 8–12 weeks: booking appointment
- 11–14 weeks: dating scan, with optional screening
- 16 weeks: screening results
- 18–21 weeks: the 20-week screening scan
- 24–28 weeks: gestational diabetes test if you're at higher risk
- 25 and 31 weeks: first baby only
- 28 weeks: blood tests, and an injection if you're at risk of rhesus disease
- 34, 36 (baby's position), 38, 40 (first baby) and 41 weeks
Vaccines: whooping cough from 16 weeks, usually around the 20-week scan; RSV from 28 weeks, offered all year; flu in season.
This schedule is informational and is not a substitute for medical advice; your provider sets your actual appointments. Don't wait for your next visit if you have bleeding, leaking fluid, severe belly pain, a bad headache or vision changes, a fever, or your baby is moving less. Call your provider or labor and delivery right away, and call 911 in an emergency.
Frequently asked questions
How often are prenatal appointments?
In a typical US pregnancy, about monthly until 28 weeks, every two weeks from 28 to 36 weeks, then weekly until birth. Higher-risk pregnancies may need more visits.
When is the anatomy scan?
Usually between 18 and 22 weeks. The tool shows the exact dates for your pregnancy.
At how many weeks is the glucose test?
Usually between 24 and 28 weeks, or earlier if you have risk factors for gestational diabetes.
When is the Group B strep test?
ACOG recommends it between 36 weeks 0 days and 37 weeks 6 days. It's a swab of the vagina and rectum.
When should I get the Tdap shot?
During weeks 27 through 36 of every pregnancy, preferably early in that window, according to CDC and ACOG.
Can I add the schedule to my phone calendar?
Yes. The .ics button downloads every item with its date range, and you can import it into Google Calendar, Apple Calendar or Outlook.
