TTC and drinking alcohol

So im one month ttc now. I have 2 kids and currently ttc for baby number 3. SO really wants a 3rd and last baby and i do too. And he got me taking prenatals and maca and vitex now (just getting off the two months injection and i have no period). The issue is i drink, i don't drink alot but i like drinking over the weekend. I like drinking. I know i can stop once im pregnant, but can i drink and ttc?
