Low income housing question

So I just got my first place and moved into a low income apartment. I have no one to ask and it’s bugging me, well I just moved in here two weeks ago. I got a letter saying I have to come into the office next week and I have to bring these forms in that they sent about recertification and my income which currently I have no income nothings changed except I got WiFi which my Aunt pays for until I find a job. I’m pregnant and SO currently looking and applying everywhere. But could it be that they got notified I got WiFi and want to change my income?
