I've been coughing up little jelly balls and they are clear im concerned what could it be?

Cough. Cough could be many things but the four most common are 1. Medications; 2. Asthma; 3. Post nasal drainage; 4. Reflux/heartburn. You really should see an allergist or an ENT for further evaluation and treatment. Remember, based on your age....It could be a combination of all four.
