Sure. When you do an apnea dive, you breathe in one atmosphere of air. At this point the air is in a semi-rigid container. IOW, it's not as affected by ambient pressures as a regulator would be. When you breathe off of a regulator, you're filling your lungs with air at ambient pressure.
Secondly, how long will you be down? For every two minute dive, you're probably going to have a 10 minute recovery.
Unless you do something to really change these two parameters, your chances of getting the bends from apnea diving is zero, nada and squat in precisely that order.
