Is getting married at a young age so bad?

Im 17 about to be 18 and my boyfriend’s 20.We been together for 3 years, he is in the airforce while im trying to graduate from highschool. we are talking about getting married. I wonder if it’s a bad thing to get married at such a young age. I think if your in love and you love every little thing about them and wouldnt mind spending your life with them then why shouldnt you go for it. Once i graduate i’d like to move to utah and live with him and possibly get married. After a year off from school when im all settled down,id like to go to collage and go to nursing school. Someday i would love to have children but i like to have a stable job first. I know that my boyfriend can support me in anyway he can.

Do i wait ?
