Condom Breaking

I'm a teenager, and there's no doubt in my mind about wanting to have sex with my boyfriend, we've been together for almost a year and a half, and I'm mentally ready for it. I plan on telling my parents and talking to them about it, but I'm afraid of the condom breaking. I know, it's kind of silly to think about, but at the same time I have anxiety-- (which has gone down tremendously over the course of this year) but I don't want it to spike up again with me thinking about the possibility of me getting pregnant. Can you give me some reassurance or something? Thank you in advance...
