BAH Back Pay

So, my husband and I got married in January of 2024 and didn’t apply for BAH because I was about to PCS (we were in hawaii). I want to know if we will still get back pay because I’m hearing so many different answers from NCOs saying we get back pay from the first 6 months of being married. However, people are also saying we get back paid from the day we got married to now (which seems false). I just want to know how it would work we were both E-4’s btw(Army). I’ve tried looking at the regulations but I can’t find anything. Will we get back pay or is there a regulation I can check for information?
