Terrible timing 😒

Lindsey
So I believe my ovulation day was this past Friday/Saturday (6/24 or 6/25)..my DH and I leave for vacation this Friday (6/7 DPO) so it will be too early to test, but we are going to be gone until I'm 14/15 DPO..we will be with family on vacation, none of which know we are trying because we want to keep it between us until the time is right and I am actually expecting. 
First, would you test while we are gone discretely? Or suffer through and wait until 15/16 DPO when I am home and test? We are sharing a room with my BIL and his girlfriend, so I would have to be very secretive in the bathroom.
Second, we always drink on family vacation..not tons, but beers on the beach, mixed drinks out to dinner, etc. I'm worried someone might put two and two together if they see I'm not drinking at all on vacation just to be cautious..thoughts?Â
