3 Weeks Pregnant

Baby at 3 Weeks Pregnant 🚼

Let's get this party started! Welcome to our weekly series on pregnancy from a natural perspective.

Why are we starting at week 3? Well, your due date isn’t calculated from the precise moment of conception, but rather from the first day of your last menstrual period—which means you’re not actually pregnant at all during weeks 1 and 2 of your pregnancy.

Week 3, however, is when all the magic happens.

Between 12 and 24 hours after Papa’s sperm meets your egg, your genetic material has combined, baby’s sex has been determined, and your single-celled “zygote” has started traveling through the fallopian tube.

Once arriving inside your uterus—anywhere from 3 to 5 days later—baby will implant into the uterine lining, snuggling deep into the sponge-like tissue, making herself (or himself) a cozy home.

Let's the games begin! ⛳

You at 3 Weeks Pregnant 🚺

So what's going on with you in week 3? In a word (or two): Not much.

It’s still way too early to detect your little guy or gal via a home pregnancy test—your body likely hasn’t started producing hCG, and most mamas won’t even realize they’re pregnant for several more weeks.

Some women, however, may experience some very early signs of pregnancy, including fatigue, nausea, a heightened sense of smell, or light spotting. Your breasts might also feel full or tender, and your areolas may seem darker.
