Why It Happens

One of the earliest signs of pregnancy. Estrogen and progesterone prepare the breasts for milk production, increasing blood flow and fat layers.

Safe Home Remedies

  • Wear a supportive, wire-free maternity bra.
  • Avoid tight clothing that presses on the chest.
  • Apply a cool compress to sore areas.

⚠️ When to Contact a Doctor

Rarely a medical emergency. Contact your doctor if you detect a hard, painful lump or experience nipple discharge that is bloody.
