Drinking at 10dpo?

Lee
So on Saturday il be 10dpo and there's a big event happening that no doubt will involve drinking. I've been having a few symptoms especially the tender sore boobs! (Dont usually get sore boobs till 4 days before af and it's a different sort pain. Feels like bruising!) Af due in 7 days. Is it worth taking a test at 10dpo before I drink?
