spawned in new location in nether without a portal to get home

Playing on ps4, this has happened twice now, Keep in mind if already got to the nether countless times,I go into my nether portal like I normally would but when I come out on the other side I spawn in a completely new location (not my normal nether survival shelter I built). this sucks but what's really aggravating is the fact that when I spawn in a new portal to get back home doesn't... so im not only lost but stuck and have to either sacrifice my items or load a previous save and lose tones of progress. not happy please pleas fix this... please ....sorry if im being rude
