It sounds like an obstructive episode, but it's difficult to say that it's an apnea. If it's happening when on your back, try sleeping on your side or stomach, if possible (you're probably already doing this). Also try to avoid eating or drinking any alcohol within 3-4 hours of bedtime.
All humans stop breathing once in a while and wake up to various degrees. If you feel tired or have any anxiety or depression symptoms, then you should be seen by a sleep doctor to rule out obstructive sleep apnea. It's been shown that even young, thin women that don't snore can have significant sleep apnea.
I forgot to add that I do not drink or smoke.
