Boss still haven’t paid me

Ik this is unrelated to this group but I just want this post to be seen a by a few hopefully. So I get pay every 2 weeks I’m a college student barely making ends meet, I can only afford to work two days a week since my schedule is so tight. However my boss was suppose to pay me yesterday on Monday and she didn’t mention anything about it, now today Tuesday I went to work already finish my shift from 2pm and still haven’t gotten paid. I brought it up earlier today around 12pm and she had told me that she haven’t gotten around to pay me because she’s been doing a lot. But it’s not fair for me because I always made sure to be there on time do what I’m suppose to do at work but when it’s time to pay me it’s not treated like a priority… also I have bills to pay, I’m just so annoyed and i feel like this is just going to cause problems
