Visit the dentist: You are young to have a loose wisdom tooth, unless you have a rare form of gum disease, but that would affect other teeth as well. It is hard to say what is going on, could be the gingiva is swollen. The dentist need to examine your teeth and advise you.

See a dentist: Your wisdom tooth might be broken and needs immediate dental attention. When it comes to a broken wisdom tooth, time is of the essence. A broken wisdom tooth left as is can lead to many problems, infection is most common. See your dentist immediately to prevent future complications. No problem with breastfeeding. Good luck.

Loose wisdom: A loose tooth be it a wisdom tooth or other tooth at your age is an issue that needs to be evaluated. Call your dentist and make sure you do not have some sort of infection associated with this tooth. If the tooth needs to be extracted and you are put on narcotic pain relievers you may have to pump and dump for a while.
