HELP! Condom broke problem

So me and my boyfriend had sex last week and the condom broke , he didn’t nut but I’m a procrastinator so I went and got a plan b anyways because you can get pregnant from precum. Today he convinced me to do it again and I told him the condom better not break .... and it broke . I also believe my ovulation day was yesterday or a day ago . Should we get another plan b or should I be fine . He believes I didn’t need the first one but it’s just a lot for me to think about . And should I convince him to get it today or should tomorrow be fine , he’s not totally sure if he can do today
