TWW & drinking

So I'm in my TWW currently. Currently on CD 28 and I'm supposed to start AF May 10th (cycles are typically 30-35 days). I went out tonight and had 2 glasses of wine. I'm going out tomorrow and will probably have 2 glasses of wine (celebrating some things 😉) and then Saturday is my friends 30th birthday so she wants to go out to the bars. I typically don't drink like at all. Maybe 1-2 glasses of wine/week if at all! Will the 2 glasses of wine I had tonight affect anything? And what about if I drink on Saturday for my friends birthday? Should I test before we go out?
