Feeling terrible😞

I called my fertility nurse yesterday and told her I was 3 days late for AF and she said the medicine I was on this cycle could have delayed it and she was pretty much expecting me to get AF since I had a bfn yesterday (15dpo) Tonight I drank almost a whole bottle of wine and now I feel terrible because I realized there is still a chance I could be pregnant since AF isn't showing ANY signs of coming. I'm usually on a 24-25 day cycle...I'm going into CD 29. Not sure how to feel. 😞
