Teen pregnancy

I’ve made the mistake of having unprotected sex with a couple different people in the past few months however I’m on the pill and take it regularly. I take it for three months at a time and don’t get a period but I should get one when I take a week off before starting my next pack, however two weeks ago was when I should’ve gotten it and it never came. I have a little bump looking thing where everyone gets a baby bump and it looks like one. I’m taking a test tomorrow but if it’s positive what do I do? I’m still in high school and don’t know who the father would be :// I’m super super scared
