TTC bachelorette weekend

My fiancé and I have been planning to conceive as close to our wedding date as we can for the last 6 months. Turns out that my anticipated most fertile day just so happens to fall on the first day of my bachelorette weekend. I don’t typically drink to begin with, but given the occasion, I wanted to be able to have some drinks and have fun. Is it possible that if I conceive that day and drink that night and the next night, that it could affect the potential pregnancy?
