TWW -Advice/Answers

AF is due on the 25th and I have been feeling a little weird but no spotting or implantation bleeding it's been quite the celebratory month so I've been having drinks a couple times a week the last 3 weeks. I'm starting to be paranoid if I am pregnant that drinking even before I have implantation (that I know of or a missed period) is going to mess with a potentially growing zygote/fetus.... I've read drinking doesn't really have an affect if you haven't even missed your period yet or had a positive test. Any insight? Has there been any mothers on here that drank til they found out an unplanned or planned pregnancy? And the outcome?
