i am 13 and had protected sex. am i pregnant?

my boyfriend and i recently tried having protected sex. the condom didn't split or anything but i am really worried because my period is almost 2 weeks late. i'm freaking out. i'm really really stressed and cant stop crying at the thought that i might be pregnant. nothing went in or near me and i cant help to think that maybe it did. i am really stressed and have been non stop crying over this. i get a tiny bit of cramping but i also have breast tenderness and i know that this is pregnancy and menstrual symptoms. i do not want to tell my parents any of this because they will freak and kick me out. i just want a answer to this, ASAP. i am so scared and have no clue what to do. i'm 13 after all. i dont want to get a pregnancy test because i dont want to freak myself out because if it is positive i would not know what to do and freak out even more. PLEASE SOMEONE HELP! im so scared :(
