Week 4

This is the week when things get real. That little fertilized egg (now called a blastocyst) may have nestled into your uterine lining—and your body is about to start whispering hey, something’s happening here.

Some call this the first official week of pregnancy—even though the countdown technically started three weeks ago.

What’s Happening in Your Body?

If implantation is successful, your body begins producing hCG (human chorionic gonadotropin)—aka the pregnancy hormone. It’s the same hormone that pregnancy tests look for.

Your uterine lining is thickening, your hormones are shifting, and your body is gearing up to grow a baby, even if you don’t quite believe it yet.

Could You Get a Positive Test?

Maybe! By the end of this week, early detection tests can sometimes catch a positive result. But every body’s timeline is different.

If the test is negative and your period is late—don’t panic. It might just be too soon. (And yes, this is the part where you’ll want to test every single day. We get it.)

Common Early Symptoms

Not everyone gets symptoms in Week 4, but some people report:

• Tender breasts

• Mild cramping or spotting (from implantation)

• Fatigue

• Mood swings (fun!)

• Feeling bloated or just “off”

But again, some people feel nothing—and still go on to have perfectly healthy pregnancies.

What You Can Do This Week

• Take a test if your period is late and you’re curious

• Start a journal—even if it’s just to vent about the waiting game

• Keep your routines steady: rest, eat well, move your body gently

And if you do get a positive test? Take a moment. Breathe. Smile, cry, or panic-laugh—whatever feels right.

Real Talk

This week is a lot. Waiting. Wondering. Staring at faint pink lines under three different lighting angles. Wondering if your sore boobs mean pregnancy or just pre-period drama. We’ve Googled it all at 2 a.m.

Whether you’re pregnant or still waiting—you’re in it now. And we’re right here with you.
