Drinking alcohol while trying to conceive

Kelly • Pregnant with my 3rd child due 16 th of Feb I have a 3 year old daughter and in November 2015 I had a Mmc with my son 💙
I'm not a heavey drinker but I like a drink the weekends maybe a bit to much sometimes but since my last af I haven't touched a drop and got a posative opk today do you think that me cutting out the alcohol this month could inprove my chances? Does its affect your chances do u think ??
