Teen Pregnancy

Recently I've gotten a boyfriend and we're teenagers, i know hormonal and everything, so we've been having sex or other activities, and my period was 10 days late, i had to take my first pregnancy test right before i went to work and it really scared me and made me feel lonely, idk why i would post this at all i just needed to rant to someone because no one else knows but me and him, it came back negative thank god but it was a small disappointment because i want to start a family with him, just later in life. We're both young, him 17 and me 16, and he is going into the military as well as myself in a year, it's stressful and a huge relief but i hope to never go through something like that
