It is probably too late for the morning after pill.

Hi. Ok so two days ago I had a drunk one night stand. First time we had sex the condom was too tight and popped. He pulled out and put a new one on and even then pulled out and came outside me. The next morning we ran out of condoms and had sex without a condom. Between stopping and starting I'd say this went on for 20mins or so. He came outside and claimed that there was no precum. Bear in mind too that we were both drunk that night. He definately didnt come inside me but there may have been precum. Im worried though. Im not on the pill and it is probably too late for the morning after pill. I was on day 27 of my 34 day cycles although sometimes my cycles can be as long as 45 days as I am very irregular. Advice? Please help Im really worried :(
