how does anyone afford uni?

and i’m not just on about the overall costs i mean like, how does anyone afford to live (food, rent, utilities) whilst they’re in uni. i planned to do a nursing degree then the shortened route midwifery degree, but then got pregnant so it will be a while away and also i’ll have to parent, do coursework and placement. can any parents weigh in on this? will i still be entitled to my universal credit if i am in university?
