About this symptom

Tender Breasts

Swollen or tender breasts are pregnancy symptoms which can begin very soon after conception. This might be your first clue that you are pregnant! Increasing levels of hormones cause increased blood flow and changes to the breast tissue. As milk ducts and milk-producing cells develop your breasts may feel swollen, tender or very sensitive to touch. You may also feel tingling, throbbing, burning sensation or itchiness. Your breasts may also grow in size, feel heavy or change in shape.

As your body adjusts to the new surge of hormones the pain should subside. Soaking in a warm bath may help alleviate some discomfort, and consider sleeping in a comfortable bra. As your breasts change in size be sure to always wear a well-fitting supportive bra. It is recommended you have your bra professionally fitted.
