Breast Pain and Size Changes During Early Pregnancy

Breast tenderness during pregnancy?

Hello Doctor: I am approximately seven weeks pregnant, and the most noticeable change I have experienced is breast tenderness.
My breasts, particularly around the nipples, are very painful, and even turning over in bed at night causes discomfort.
Is this normal? Additionally, I have recently noticed a significant size difference between my breasts, which I did not experience before pregnancy.
Is this a cause for concern? Should I see a doctor?

Dr. Lü Lizheng reply Obstetrics and Gynecology

Hello, Xiao Hui! Due to pregnancy, the levels of female hormones and progesterone in your body are rapidly increasing, both of which can promote breast growth and tenderness.
This condition usually improves on its own after some time.
It is common for individuals to have asymmetrical breasts, but the difference in size may become more pronounced during pregnancy.
If you are concerned, you can consult a breast surgeon for a breast ultrasound examination.
Wishing you good health, Dr.

More Info

Breast pain and size changes during early pregnancy are common experiences for many women, and they can be attributed to the hormonal changes that occur in the body. When you become pregnant, your body undergoes significant hormonal shifts, particularly with increased levels of estrogen and progesterone. These hormones play a crucial role in preparing your body for breastfeeding and nurturing the developing fetus.

The breast pain you are experiencing, especially around the nipples, is often referred to as mastalgia. This discomfort can manifest as tenderness, swelling, or a feeling of heaviness in the breasts. It is not unusual for this pain to be exacerbated by physical activities, such as rolling over in bed, as you mentioned. The sensitivity of breast tissue can vary greatly among women, and some may experience more pronounced discomfort than others. This condition is generally considered normal and is expected to improve as your pregnancy progresses, particularly as your body adjusts to the hormonal changes.

Regarding the size difference between your breasts, it is also quite common for women to notice asymmetry in breast size, especially during pregnancy. Hormonal fluctuations can lead to varying degrees of breast tissue development, which may result in one breast appearing larger than the other. While this can be concerning, it is typically a normal variation and not indicative of any underlying health issues. However, if the size difference is significant or accompanied by other symptoms such as lumps, persistent pain, or changes in the skin texture, it would be advisable to consult a healthcare professional for further evaluation.

If you are feeling anxious about your symptoms or if the pain becomes unbearable, it is always a good idea to reach out to your healthcare provider. They can perform a physical examination and, if necessary, conduct imaging tests like a breast ultrasound to rule out any potential issues. While most breast pain during pregnancy is benign and resolves on its own, your comfort and peace of mind are important.

In summary, breast pain and size changes during early pregnancy are typically normal and result from hormonal changes. While these symptoms can be uncomfortable, they usually improve over time. If you have any concerns or if your symptoms worsen, do not hesitate to seek medical advice. Your healthcare provider can offer reassurance and ensure that both you and your baby are healthy.
