Please help me

My period is late I’m so scared that I might be pregnant. I don’t know if I’m pregnant or just stressed or that it’s because I went from doing nothing to doing so much lately but I can’t be pregnant. I’ve been crying so much the past couple days and I’m too scared to take a pregnancy test. I don’t know what to do. I can’t tell my boyfriend that I’m scared because I know how feels if I were to get pregnant. He would want me to get an abortion but I’m against abortions because of what I believe but don’t get me wrong if you want to or do I won’t judge but I couldn’t live with myself if I had an abortion. My boyfriend basically believes that me being pregnant before we’re married would ruin our lives and I don’t think he think that I could do it on my own and honestly I don’t know if I could. I’m only 19 and I’m so scared. I don’t know what to do
