drinking definitely affects fetus if you are pregnant..u shoul avoid alcohol in pregnancy
as it affects mental physical and functional development of the child..and moreover alcohol in first 3 mths is still more dangerous to baby..
coming to your problem, actually we cant say exactly like how much quantity of alcohol affects the child ..and if 100% effect will be there on child..but i suggest since you are still in early stage of pregnancy u have time even nw to avoid ur habit and go into safe pregnancy..as your baby s brain still have time developing..
so b away from alcohol to have a healthy baby atleast from now on.
all the best..
