If you have noticed a change in the smell of your vagina after giving birth, it could be due to hormonal changes and natural postpartum recovery. However, if this change persists or is accompanied by other symptoms such as pain, itching, or unusual discharge, it is important to consult with your doctor to rule out any potential infections or complications. It is always better to address any concerns about your health with a medical professional to ensure proper assessment and treatment, if necessary.
