Ten Moons
Pregnancy home

First trimester

Week 3

37 weeks to go

Eight short cards a week — the baby, your body, and you. You can read them in ten minutes and close the app.

Baby

What's growing

Fertilization and travel

A single cell becomes a blastocyst over ~6 days as it travels down the fallopian tube toward the uterus.

Body

What's changing in you

Mostly invisible

Hormonal cascade has begun, but most people feel nothing yet. Trust the timeline.

Source: Williams Obstetrics, 26th ed. (Cunningham et al., 2022)

General info — not personalized medical advice.

Brain

Maternal brain

Magical thinking is normal

Bargaining, wishing, scanning your body — common in early pregnancy and not a sign of anxiety.

Source: O'Hara & Wisner, Best Practice & Research Clinical OB/GYN 28(1), 2014 — Perinatal mental illness

Bond

You & baby

An idea, not yet a person

It is okay if it does not feel real yet. Bonding before sensation is the rule, not the exception.

Partner

For your partner

Share the test

If testing, decide together — alone or together, when, how. Small co-decisions build co-parenting muscles.

Reflection

60-second prompt

What part of you is hopeful?

Name it. Even quietly.
