Stayci, sometimes women lactate without pregnancy, there are a few reasons why it happens and one of those reasons might impact on your TTC journey (hormonal -too much prolactin in your blood) so best to get this checked.

The other reason why you need to take this seriously is because any discharge from your breast is a breast change, so you need to get it checked to rule out the very slight possibility of breast cancer. Most breast changes are not cancerous, but in the very remote chance that it was, prompt medical attention is the very best advantage you can give yourself.
