Anyone!!!!

So ive been feeling off for a few days. Super tired, nauseas, sorta crampy, peeing all the time, bloated, back pain and a messed up sleep schedule. My boyfriend and I have sex all the time and we only ever do the pull out method. My period is 4 days late. I cant buy a pregnancy test because my mom would find out about it somehow, she finds everything. Are these symptoms of pregnant or more so period?
