Daffodil
5.4 cm (2.1 in)crown to rump
The Daffodil (~5–6 cm face) brings a clear note of brightness to the close of the first trimester. Brightness here is an image, not an instruction for how you should feel.
This week, inside
The fetus is about 5.4 cm from head to bottom. Internal organs and muscles have grown, the skeleton is beginning to harden from tissue into bone, and the sex organs have formed.

Small things that help
Mark the end of this chapter in a way that fits your story: a photo, a walk, a private sentence, or nothing at all. Gather appointment notes in one place so they are easy to find later.
For the record
What would you place in a time capsule from the first trimester?
Zohra asks one of these every week, and keeps your answer. A year from now it is the part people say they are most glad they wrote down.

Zohra draws this same flower in the app, at this same size, and keeps what you write beside it — with your bump photos, the letters, and the sounds from your appointments.
