Please help!!!!

My husband had a couple drinks last night (more than 5) and I'm worried if we try to conceive today we will have little to no chance of getting pregnant and I supposedly ovulate in 2 days. We've had sex for the past 5 days in a row and I was going to hold off today since he was drinking last night but I'm not sure if his drinking for one night (which he hasn't done in a while until last night) has an actual affect on the sperm? Thanks!!
