Why Do I Get Sore Boobs?

Sore breasts are a common symptom of both PMS (premenstrual syndrome) and early pregnancy. However, in the context of fertility, sore boobs can sometimes be a sign of low progesterone levels.

Progesterone is a hormone crucial for preparing the uterine lining for implantation and maintaining a healthy pregnancy.  When progesterone levels are low, the lining may not be receptive to a fertilised egg, making it harder to conceive or maintain a pregnancy. Certain foods can support healthy progesterone production. Include vitamin C rich fruit like berries and tomatoes, healthy fats like avocado and nuts, cruciferous vegetables like broccoli and cauliflower, and whole grains in your diet. Chronic stress can disrupt hormone balance, including progesterone. Practice relaxation techniques like yoga, meditation, or deep breathing to manage stress levels.

Sore Boobs in Pregnancy

During early pregnancy, your body experiences a surge in hormones like oestrogen and progesterone. These hormonal fluctuations can cause breast tenderness and swelling, similar to what you might experience during PMS. Your breasts start preparing for lactation (breastfeeding) very early in pregnancy. This includes increased blood flow to the breasts, which can lead to feelings of heaviness, tingling, and tenderness. The Montgomery glands (the small bumps around the areola which is the darker area around your nipple) can become more noticeable during pregnancy due to hormonal changes. They may also feel sensitive or sore. Some women experience breast tenderness shortly after implantation, when the fertilised egg attaches to the uterine lining. This can be one of the earliest signs of pregnancy.
