wrong confirmation number?

i’m kinda worried because i’m unable to view my flight from SLC to HRL like AT ALL. i cant check the flight details both in app and on website. I have another trip scheduled for a month from now and i’m able to view it just fine, except for this trip. (12/19) Im unsure of what to do because it gives me an error everytime i try to click on it, i’m worried i won’t be able to check in if i can’t even access it on the app. Is this an error with my confirmation #? since i can view the other trip just fine. and to add i haven’t received any sort of email for this flight either, which i booked over the phone. which is weird because im pretty sure southwest sends you an email about your trip a few days prior
