should I be ok?

So my boyfriend and I are young(21 and 19)  but we really do care for each other. When it comes to sex we are always safe and responsible. When we have sex, we use condoms, he doesn't cum in me, and sometimes I use spermicide. Usually when I'm close to ovulation we try not to have sex, but if we do I use all three of them. Would I still be at a high risk of pregnancy using all those if I'm close to ovulation. Personally I think we would be safe because my boyfriend and I are definitely not thinking about kids.
