😷 Help with Dos & Dont's TTC

So my husband and I are TTC baby #1.. We both are very active and like to have a good time. If we have conceived a few days prior to drinking over the weekend is that harmful to the baby?! How soon before you know if your pregnant should you stop drinking? Not that I drink a lot, maybe a glass of wine with dinner.
