Chances of pregnancy??

My boyfriend and I had intercourse on the first days of my ovulation, but not on the pick day. He finished inside me  all those days. So I am wondering if I there is a chance that I may be pregnant or not?? Also, I have to add that we both have crazy life styles since we both work in the night life industry, so there is a lot of alcohol involved. I don't know if that would affect the conception process
