Test before Vaca?

Crystal • 1st IUI: 11/14/15, BFP 11/27/15! Miscarried 12/4/15. 2nd IUI: 12/20/15, BFP #2 1/2/16!!!
We have been TTC for 7 cycles now. I'm headed for vaca with my husband's family next week. We leave when I'll be at 9 dpo. Alcohol is expected on this trip and they know I'm not shy about having a drink typically. Either way, by the time the trip is over, I'll probably know if I'm pregnant or not. I've been a screaming, crying disaster when my period comes the last 2 cycles... Nobody knows we are TTC (been married 5 years and didn't want to add any extra pressure) so I don't want to tell the family. If it were you, would you test at 9 dpo anyway? I am not typically an early tester... Can you justify why/ why not? I need help to avoid some heartache... This is not as easy as I thought it would be. 😢
