I took a test at the pharmacy, but I can't do it

I haven't had my period for two weeks, and I was quite stressed during the expected dates. Today, I finally gathered my courage and bought a pregnancy test from the pharmacy, but I'm still hesitant to find out the result. Moreover, my boyfriend is completely unaware of anything. I'm scared about what I'll do if it's positive. If my mom finds out, I probably won't even be able to come home, let alone build the future of my dreams. Do you think I should do it right away, or would it be better to wait?
