3 Weeks Pregnant – Fertilization & Implantation Starts

What’s Happening at 3 Weeks Pregnant?

3 Weeks Pregnant – This is the week when pregnancy actually begins. The sperm meets the egg, and fertilization takes place inside the fallopian tube. The fertilized egg is now called a zygote.

• The zygote contains all genetic material from both parents
• It starts traveling to the uterus (3–5 days journey)
• Once in the uterus, it prepares to implant in the lining
• Hormone hCG (what pregnancy tests detect) begins after implantation

You are officially pregnant this week, although you won’t get a positive test result yet.

Early Pregnancy Symptoms at Week 3

Some women feel very early signs even before a missed period, while others feel nothing.

Possible Symptoms:

• Implantation spotting (very light pink or brown)
• Mild cramps (like PMS)
• Tender or swollen breasts
• Mood swings or irritability
• Increased urination or fatigue
• Slight rise in body temperature

These signs are easy to miss or confuse with period symptoms.
