Tender Breasts (Underarms)

Very Early Pregnancy Symptom

Symptom Details

Swollen or tender breasts are pregnancy symptoms which can begin very soon after conception. This might be your first clue that you are pregnant! Some women report that they feel it most in the sides of their breasts or under arms. Some describe it as affecting the entire breast. 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 professional fitted.

**NOTE: Data for 15-21 dpo tends to be lower than expected as many women stop tracking symptoms after a positive pregnancy test.
