To drink or not to drink ... that is the question 🤷🏻‍♀️

Im currently 8DPO and AF is due 12/2 .. I have a Xmas/wreath making party on 12/1 to attend and it involves lots of fun and alcohol lol.. I’m not sure if I will get a BFP before that in order to know if it’s safe to drink or not.. what if I test and it’s negative but then I get a positive a few days later.. how many of you ladies have got bfn at 13dpo but then a bfp a few days later.. #totallyoverthinkingit
