pls help

I think I just need some reassurance. I'm 5 days late, and I'm pretty much never late for my period and I'm pretty regular so this is unusual for me.  My boobs are super sore and I've had cramps on and off for the last few days but still no period. My bf and I always use protection but still I'm so worried. I know the right thing to do is to just take a test but I'm too afraid to even see the answer. I don't even know what I would do if I were infact, pregnant I'm no where near ready for a child....
