My Husband Tells Me That When I Sleep I Seem

My husband tells me that when I sleep I seem to inhale normally, but when I exhale I pause a few times during exhalation. He says my exhalation is not one complete step but is broken into short "mini" puffs and the exhalation is much longer than inhalation. Is this sleep apnea? I do not smoke or drink alcohol and I am not overweight. I do suffer from extreme fatigue during the day. Thanks.
