Supposed to go out for drinks around the time I would be implanting?

So my s/o and I are ttc, but we’ve been really busy this month and only got to BD once during my fertile window, on tuesday. I’m supposed to ovulate today according to glow, though from my symptoms I believe I ovulated yesterday. We will also BD tomorrow. I realize we probably don’t have good chances this month. I’m supposed to go out with some coworkers next Saturday (16th) for drinks, and if we conceived I should implant around the 14th-19th. If I go and don’t drink, they’ll definitely know somethings up, and I’m not good at lying. Should I cancel? Or just get 1 or 2 light drinks? If I go I’ll definitely test Saturday morning, but it’ll be so early I likely wouldn’t get a positive even if I did conceive.
