Has anyone ever conceived after binge drinking one night during luteal phase?

My husband and I have been ttc for 7 months and are getting a little discouraged. We are both very healthy active 28 year olds. Maybe once every month Or every other minute month we have a get together with friends and I drink a little too much and have a hangover the next day but then life carries on. We have been trying very hard eating right and I know my cycle. I'm wondering if anyone has done that and still been fine and gotten pregnant or if it's hurting our chances of conceiving. Thanks for you help.
