Scared.. Abortion?

Kind of worried I'm 6 days late and my period shows no signs of coming. I'm very hesitant to take a pregnancy test because the last time I thought I was pregnant my boyfriend basically told me we shouldn't keep it because we're young (I'm 18 he's 21) and wanted me to get an abortion. I'm scared because I've been a little late before but it's never been this long. I'm scared because if I am pregnant I don't want him to tell me that again. I'm not dumb I know we're young and we have plenty of time to have kids and everything but I know if I can handle getting an abortion it kills me to think about losing a part of me like that. And I'm thinking about how my mom would react if I told her I was pregnant.. Can someone give me advise please? Has anyone went through this or had an abortion?
