My period is LATE/ Update

I was supposed to get my period on the 22nd and its the 28th. I’m soo scared if I’m pregnant because I know my parents would kick me out. I don’t know if i should keep the baby if I am pregnant because my boyfriend already has a kid and I don’t want to make him look bad. Help please I’m only 18 I need advice 😭.

UPDATE

So I took the test yesterday like recommended and it was negative but the big question is when will i get my period though. The longer I have to wait the longer i think it’s a false negative.
