Breast Leaking (Colostrum) at 6 Weeks Pregnant

Leaking of colostrum — the first breast milk — from the nipples is normal from around 14–16 weeks of pregnancy and increases as the due date approaches. It is a positive sign that the breasts are preparing for feeding.

👶 What's Happening at Week 6

Your baby is now the size of a lentil.

  • Facial features begin forming — dark spots where eyes will be, openings for nostrils.
  • The jaw, cheeks, and chin are taking shape.
  • Tiny fingers and toes start to form from the limb buds.

🔬 Why You're Experiencing Breast Leaking (Colostrum) at Week 6

  • Breasts begin producing colostrum in the second trimester under the influence of prolactin
  • Oxytocin release (from arousal, orgasm, or warm showers) triggers milk ejection reflex
  • As the due date approaches, prolactin levels rise and leaking increases
  • Breast stimulation causes temporary increase in leaking

💊 Relief Tips for Week 6

1
Breast PadsDisposable or reusable breast pads worn inside the bra absorb colostrum leaks discreetly.
2
Well-Fitted Maternity BraA supportive bra holds breast pads in place and reduces nipple friction.
3
Avoid Breast StimulationIf leaking is frequent or bothersome, avoid unnecessary nipple stimulation.
4
Normal HygieneKeep the nipple area clean and dry to prevent irritation or cracking.

Frequently Asked Questions

When do breasts start leaking colostrum?

Colostrum production can begin as early as 14–16 weeks, though not all women notice leaking. It becomes more common in the third trimester.

Should I collect colostrum during pregnancy?

Some providers recommend 'antenatal hand expression' (harvesting colostrum) from 36 weeks if there are concerns about feeding. Do not attempt this earlier without provider guidance, as nipple stimulation can trigger contractions.

What does colostrum look like?

Colostrum is thick and usually yellow, golden, or orange-ish in color (sometimes white or clear). It is different from mature breast milk.

Is leaking a lot of colostrum a sign that I will have a good milk supply?

Not necessarily — the amount of colostrum that leaks during pregnancy has no reliable relationship with milk supply after birth.
