Spotting at 40 Weeks Pregnant

Light spotting (small amounts of pink or brown blood) can occur during pregnancy, especially in the first trimester. While often harmless, any bleeding during pregnancy should be reported to your healthcare provider.

👶 What's Happening at Week 40

Your baby is now the size of a small pumpkin.

  • The baby is fully developed and ready for life outside the womb.
  • Lungs are producing enough surfactant for independent breathing.
  • The skull bones are soft and can mold for passage through the birth canal.

🔬 Why You're Experiencing Spotting at Week 40

  • Implantation bleeding — fertilized egg attaching to the uterine wall (very early pregnancy)
  • Cervical sensitivity — the cervix has more blood vessels during pregnancy
  • After intercourse or a pelvic exam (contact spotting)
  • Subchorionic hemorrhage — small collection of blood between the placenta and uterine wall
  • Threatened miscarriage or early pregnancy loss

Frequently Asked Questions

What does implantation bleeding look like?

Implantation bleeding is typically very light (a few spots), pink or brown in color, and lasts 1–3 days. It occurs around 10–14 days after conception.

How do I tell implantation bleeding from a period?

Implantation bleeding is lighter, shorter, and doesn't progress to a normal flow. A period typically gets heavier over the first day or two.

Can you have spotting and still be pregnant?

Yes — many women experience light spotting and go on to have healthy pregnancies. Spotting in early pregnancy is common and often harmless.

Is brown spotting normal in early pregnancy?

Brown spotting (old blood) is generally less concerning than fresh red blood and is often caused by implantation or minor cervical irritation.
