Pulmonary Embolism Support Group
By far the most common form of pulmonary embolism is a thromboembolism, which occurs when a blood clot, generally a venous thrombus, becomes dislodged from its site of formation and embolizes to the arterial blood supply of one of the lungs. Symptoms may include difficulty breathing, pain during breathing, and more rarely circulatory instability and death.

Truthfully, no one can guarantee that you will or you won't clot again. Some folks clot once and gone on with their lives, never to clot again. (You could be one of them--I think most people are.) Others of us are less lucky.
Either way, you're more informed about clots now, you probably know what they feel like and you'll know what to do if you feel that way again, and you'll be proactive about preventing more clots in the future in risky situations. Hopefully, you'll be fine.
Congrats on your recovery! Sounds like a long road and it is great that you're finally getting off the warfarin!
