First trimester
3 Weeks Pregnant
Tiny beginnings
How your baby is developing
- If pregnancy has begun, a tiny cluster of cells is just getting underway.
- It is far too small to notice in any way.
What may be happening in your body
- Your body may be starting subtle changes you cannot yet feel.
How you may be feeling
- You may be waiting and wondering, unsure how to feel.
- Uncertainty this early is completely normal.
Worth remembering
Whether you feel excited, anxious, or nothing at all, every reaction is okay.
Something you can do this week
Gentle routines and rest can help you feel steady while you wait.
What comes next
By around week four, a missed period is often the first hint many parents notice.
