Advice about negative tests please

So my boyfriend and I just moved in together and have been talking and agreed that we aren't trying to pregnant as a mission but we are not going to do anything to prevent it, he works full time at a good paying job with benifits and insurance, that he absolutely loves I'm currently at an internship for school but have a good job lined up once I'm done (internship is paid), we have a plan if it happens and everything figured out even though we are young I'm 19 and he's 20 but tonight I took a pregnancy test a bit early because I've been feeling so off and I really expected it to be positive and was hoping it would be but it came back negative, and I was heart broken, I know we arent exactly trying and with having another year of collegei left I know it is smarter to wait but I was so sad when I only saw the one line, any tips to make me feel better because I love him more than anything and I know its mutual but he isnt much help for making me feel better :/
