Wedding at 9dpo

I’m bridesmaid at a wedding this Saturday when I’ll be only 9dpo. I’ve not been drinking alcohol during TWW just in case but people are gonna talk if I don’t on Saturday and don’t really want rumours spreading before I even know for sure if I am or not. Guessing it’ll be too early to test still which is frustrating. Any suggestions for good excuses or ways I can get around this? Also what are the best tests to try when only 9dpo? Thanks!
