7dpo and itching to test...

What is the earliest anyone has gotten a BFP after ovulation? I know today is too early, but how long should I wait? AF due next Saturday 3/14. Lots of plans this weekend and not sure if I should skip the booze altogether, have one or two, or wait for a BFP to not drink. Sorry, lots of questions all in one post! Comments please!!
