There are no contraindications to treating a yeast infection while breastfeeding and having recently given birth. It is important to seek treatment for the infection, as there are medications that are safe to use while breastfeeding. If you are prescribed a medication, make sure it is compatible with breastfeeding. If you experience symptoms such as fever, urinary issues, abnormal vaginal discharge, or abdominal pain, it is important to consult a healthcare professional.
