Emergency, Plan B?

Hi so the bf and I just had sex and we tried a new non latex condom because I’m allergic to latex and he came and when he pulled out the condom stayed in me. The base was still out but the only thing is I’m supposed to ovulate on the 30th (2 days) I’m pretty sure there were no holes in the condom but I’m really nervous about it, will plan B work if I take it tomorrow?? And if it does, what would be the cost to get it at PP? I got a low paycheck this week because I was in quarantine.
