How the Pregnancy Week Tracker Works
Pregnancy is measured in weeks from the first day of your last period (LMP), not from conception — which is why you're considered about 2 weeks "pregnant" before you actually conceive. A full-term pregnancy is around 40 weeks, divided into three trimesters. Enter your current week or due date and we'll show you your baby's size, what's developing, and what to expect.
Baby Size by Week (Fruit & Veggie Guide)
One of the most loved parts of pregnancy is seeing your baby compared to a familiar fruit or vegetable each week. Here's the full journey:
| Week | Size Comparison | Approx. Length |
|---|---|---|
| 4 | Poppy seed | ~0.04 in |
| 6 | Sweet pea | ~0.25 in |
| 8 | Raspberry | ~0.6 in |
| 10 | Strawberry | ~1.2 in |
| 12 | Lime | ~2.1 in |
| 16 | Avocado | ~4.6 in |
| 20 | Banana | ~6.5 in |
| 24 | Ear of corn | ~11.8 in |
| 28 | Eggplant | ~14.8 in |
| 32 | Squash | ~16.7 in |
| 36 | Romaine lettuce | ~18.7 in |
| 40 | Small pumpkin / watermelon | ~20.2 in |
The Three Trimesters
- 🌱 First Trimester (Weeks 1–12): Major organs form, heartbeat begins. Morning sickness and fatigue are common.
- 🌸 Second Trimester (Weeks 13–27): The "honeymoon" phase — energy returns, the bump shows, and you'll feel first kicks.
- 🌟 Third Trimester (Weeks 28–40): Baby gains weight rapidly and gets into position for birth. Time to prep your hospital bag!

Frequently Asked Questions
How many weeks is a full pregnancy?
A full-term pregnancy lasts about 40 weeks counted from your last period. Babies born between 37 and 42 weeks are considered full term.
Why is my baby measured against fruit?
It's a fun, relatable way to picture your baby's growing size each week. Remember these are averages — healthy babies vary in size.
When will I feel my baby move?
Most first-time moms feel flutters ("quickening") between weeks 18 and 22. It may happen earlier in later pregnancies.
Is the due date exact?
No — only about 1 in 20 babies arrive on their exact due date. It's a best estimate, and full term is anywhere from 37 to 42 weeks.
