ladies who have conceived I need advice! please read

So I'm about to be 27 my husband is turning 31 today. My cycle is 27 days and I'm on last day of AF so you know what that means! Its my fertile week next week. Calender shows 19th through the 25th for fertile window. I've been praying. Eating better. More veggies fruits taking my vitamins. I only had 3 glasses of wine Wednesday when AF was on day 3. My husband likes to unwind with beer after work when he gets home around 2 am.he typically has 3.. Last night he had 6. And I know he will be having more for his bday weekend.. Does anyone think this will affect his sperm? I've been so excited for this month and ttc. And I really hope it works out..
