Emergency contraception

So last night 6/7 my boyfriend came inside me, sex has been really painful leading up to this event and in the moment we thought it would help (I know really bad judgement on both our parts) I'm on the pill but on 6/6 I took it an hour late and 6/7 I took it on time, we are getting plan b after he gets off work, I can't stop worrying and I don't know what to do, or if there's anything I can do, but wait. What should I do?
