Hi BD, no worries
If you can hold your breath long enough to resist the temptation to breath, then (most of us) you may have involuntary diaphragmatic/abdominal contractions as your body attempts to regain control of the breathing. More advanced fdivers know approximately how many contractions they can sustain in a particular situation before they lose consciousness.
