Why Is There Still Milk in My Breasts After Breastfeeding?

Why is there still milk in the breasts?

Recently, while showering and washing my nipples, I accidentally pressed on them and noticed that there was milk leaking out.
When I squeezed my breasts, milk also came out from both sides.
My child is now over 10 months old, and I breastfed for six months.
My last menstrual period started on October 18 and ended, and I had sexual intercourse during my ovulation period.
Could you please explain why there is still milk? Is there a possibility of a breast condition?

This is a normal secretion of breast milk.
Although menstruation has resumed postpartum, lactation can still occur because the levels of lactation hormones are low enough not to inhibit ovulation.
Wishing health to both mother and child.

More Info

The presence of milk in your breasts after breastfeeding, especially when your child is already 10 months old, can be concerning but is not uncommon. There are several reasons why you might still be experiencing milk leakage or discharge from your breasts.

1. Hormonal Influence: After breastfeeding, your body may still produce prolactin, the hormone responsible for milk production. Prolactin levels can remain elevated for some time after you stop breastfeeding, especially if you have recently had a menstrual cycle or are experiencing hormonal fluctuations. This can lead to residual milk production even if you are no longer actively breastfeeding.

2. Stimulation of the Breasts: Any form of stimulation to the breasts, whether through physical touch, sexual activity, or even certain types of clothing, can trigger the release of milk. The act of squeezing or pressing on the breasts can stimulate the milk ducts, causing milk to be expelled.

3. Breast Changes Post-Breastfeeding: After weaning, your breasts may take time to adjust back to their non-lactating state. This adjustment period can vary from person to person. Some women may continue to express small amounts of milk for weeks or even months after they stop breastfeeding.

4. Residual Milk: It is also possible that there is residual milk left in the ducts that has not been fully cleared out. This can happen if breastfeeding was not fully established or if there were periods of infrequent breastfeeding.

5. Potential Medical Concerns: While it is often normal to have some milk production after breastfeeding, it is essential to monitor for any unusual symptoms. If you notice any changes in the appearance of your breasts, such as lumps, persistent pain, or changes in the skin, it is advisable to consult a healthcare professional. Conditions such as galactorrhea (excessive or inappropriate milk production) can sometimes occur due to hormonal imbalances, pituitary gland issues, or other underlying health concerns.

6. Pregnancy Consideration: Given that you mentioned having sexual intercourse during your ovulation period, it is also worth considering the possibility of pregnancy. If you suspect you might be pregnant, a home pregnancy test can provide clarity, as pregnancy can also lead to changes in breast tissue and milk production.

In summary, while it is generally normal to have some milk production after breastfeeding, it is essential to pay attention to your body and any accompanying symptoms. If you have concerns about the amount of milk, any discomfort, or changes in your breast tissue, it is best to consult with a healthcare provider. They may recommend a physical examination, hormonal testing, or imaging studies like a breast ultrasound to rule out any underlying issues. Regular self-examinations and awareness of your breast health are crucial, especially after breastfeeding, to ensure any potential problems are addressed promptly.
