Your pregnancy, one week at a time
See which week you're in and how many are left, keep a list of questions for the next appointment, and note symptoms as they come.
A pregnancy is counted from the first day of your last period, and the estimated due date is 280 days later, at 40 weeks. ACOG splits it into three trimesters: weeks 1 to 13, 14 to 27, and 28 on.[1]
Turn on Pregnancy in Her Good Days and the home screen leads with your week. Symptoms, appointments, sleep and mood come first in the Log menu, and your period tracking pauses.
What the Log shows, by stage of pregnancy
| Weeks | First in your Log menu |
|---|---|
| 1 to 27 | Symptom, Appointment, Sleep, Mood, Weight |
| 28 to 35 | Kick count joins at the top |
| 36 on | Contractions timer first, then kicks, symptoms and appointments |
Weight stays only because prenatal visits weigh you. You can switch it off or log it at appointments only, and there is no weight goal during pregnancy.
Pregnancy, in the app
Today leads with your week: the week and days, how many weeks to go, your due date and the trimester, on a card of its own.
Your 40 weeks
The Pregnancy page lays the 40 weeks out in trimesters with your week marked, the days to go and the next milestone. Kick counts, the contraction timer and the checklists sit under it.
Milestones in their week
At weeks 12, 20, 28, 36, 37 and 40 a milestone card shows on Today and the week page. At week 28 it marks the third trimester and says kick counts join your Log.
Appointments, questions, symptoms
An appointment entry holds the date, who you're seeing, the questions you want to ask and the answers you got. Symptoms come from a list (nausea, heartburn, back pain, swelling, headaches, leg cramps, trouble sleeping and more) with a strength of mild, moderate or severe.
A kick counter stops at the number you set and shows how long it took. The contraction timer records length and gap. Under the button sits the NHS line: call your midwife or maternity unit if contractions come regularly, every 5 minutes or more often.[4] If your provider gave you a different rule, type it in and it shows on the timer.
A hospital bag list
The hospital bag checklist starts with 14 items, from maternity notes to snacks. Tick what is packed, add your own, and remove anything you don't need.
Questions for your midwife or doctor
A second checklist holds questions to take to appointments, such as which scans are coming up or what to do if the baby's movements change. Add your own and tick each one once it's asked.
Private by default
When you first turn Pregnancy on, the app asks where the data should live. This phone only is the default. Backing it up to your account needs an account, and you can change your mind later on the Pregnancy page.
Notifications use generic text. On the Pregnancy page, Delete pregnancy data removes it from this phone and your account in one tap.
Moving while pregnant
The app's programs include prenatal stretching, breathing and walking sessions with Elena. Each one lists who should skip it, with a safer version next to it. ACOG says to talk about exercise with your doctor at your early prenatal visits, so ask what is right for you before you start.[3]
When it ends
From week 37 the app asks, gently, whether your baby has arrived. "Yes, baby is here" asks the birth date and switches to the after-birth view. "Not yet" hides the question for 7 days. "My pregnancy has ended" stops every pregnancy screen and reminder straight away, with no follow-up questions.
Your baby, week by week
From week 4 to week 40: the average size as a fruit or vegetable, length and weight, what's developing and one tip for the week.
This week's card on Today
Today shows your baby's size this week as a fruit or vegetable, with the length, the weight and one tip. Tap it for the full week.
The week page
Pick any week from the row at the top. Each one gives the length in inches and centimeters, the weight in pounds and grams, what's developing, how you may feel, a tip and questions for your midwife or doctor.

Questions
How is my due date worked out?
From the first day of your last period plus 280 days (40 weeks), or from a conception date plus 266 days, because pregnancy is counted as starting 2 weeks after that first day. Your provider may give you a different date from a scan, and you can enter that one instead.
Will the app tell me if something is wrong?
No. It counts and records, and it doesn't assess risk. Kicks, contractions and symptoms screens carry a line to call your provider or emergency services if you're worried.
What happens after the birth?
From week 37 the app asks whether your baby has arrived. If yes, it offers the postpartum view. If the pregnancy has ended, every pregnancy screen and notification stops at once.
