What's happening this week
Somewhere in there, three tiny specks are each picking a cosy spot to settle in for the next while. They are so small right now that all three together would sit happily on your fingertip, and yet the plan for three whole people is already quietly under way.
You might not feel any different, or you might feel wiped out in a way that surprises you — and that second one makes perfect sense, because your body has just taken on three little projects at once instead of one.
Three little wonders this week
- Your three are each just settling in, already sketching out the very first layers that will one day be skin, muscle and tiny organs.
- Three babies means three little spots getting comfy in your uterus at the same time — busy work, even this early.
- With three on board, that pregnancy test line often shows up loud and unmistakable, sometimes before you even expect it.
The triplet twist
With one baby, the tell-tale hormone climbs gently. With three, it often surges much higher, much sooner — which is why some early symptoms of pregnancy can turn up for you before your friends carrying one baby even suspect a thing.
Something to look forward to
- You're about 2 weeks from the first ultrasound where someone might actually count three little sacs.
- Three flickering heartbeats are roughly 2 weeks away — get the tissues ready.
To Mom:
Tiny poppy seeds are finding their home inside you, and your body is already doing the monumental work of welcoming three little lives at once. Be kind to yourself as you adjust to this quiet, wonderful surge of new life.
