Breast discharge can be caused by elevated prolactin levels, even if your thyroid and ultrasound are normal. You should see a doctor for a blood test to check your hormone levels and determine the exact cause.

For PCOD with difficulty conceiving and hair loss, your wife should see a gynaecologist or endocrinologist. The doctor may recommend lifestyle changes, such as maintaining a healthy weight, eating a balanced diet, and exercising regularly, to improve hormone balance. Medications to induce ovulation, such as clomiphene or letrozole, as well as hormonal treatments to regulate periods and specific therapies to reduce hair loss, may also be prescribed after a proper assessment.

It is normal for milk production to continue for some time even after a child stops breastfeeding, and it usually reduces on its own gradually. To help stop it, avoid breast stimulation (like pumping or frequent checking), wear a firm, supportive bra, and use cold compresses to relieve discomfort. If needed, a doctor may prescribe medicines like Cabergoline to reduce milk production, but this should only be taken under medical guidance.

You should consult a gynaecologist to identify the underlying cause of your irregular periods, which may include a hormonal imbalance or PCOS. Maintaining a healthy weight, exercising regularly, and following a balanced diet can help, and your doctor may also prescribe medication to regulate your periods.

Your breast and back pain one week after taking cabergoline is most likely due to temporary fullness in the breast (engorgement) and your body adjusting to the hormonal changes after stopping milk production. This usually gets better on its own with supportive care like wearing a firm bra, using cold compresses, and resting your back. If the pain becomes worse, or if you notice redness, swelling, fever, or any signs of infection, it’s important to see your gynecologist promptly.

A prolactin level of 36.8 ng/mL is mildly elevated and may cause irregular periods or breast discharge. A TSH of 3.8 mIU/L is at the upper limit of normal and may indicate borderline thyroid underactivity, which can affect menstrual cycles (periods) and fertility.
