What's your opinion?

So this has been the first real month my husband and I have been "actively" ttc and we still have a "when the time is right it will happen" attitude. So my question is this: this weekend we are going to our really good friends wedding. I am currently 7dpo and I tested this morning (I know! It's early) and it was neg.. So for this weekend would it be best to refrain from having an alcoholic drink or 2, just in case I am preggers, or do you think it's ok? Thanks in advance
