Vegas...maybe

So before I decided to do a FET I have been planning a girls' trip to Vegas the first weekend in June. There about 8 of us that are planning to go. We have yet to buy our airfare or book hotels. Tonight I saw one of the ladies that I plan to go with and she was talking about how she wanted to book her airfare soon. I feel bad that I am keeping from her that I might be pregnant then and won't want to go if I cant drink. I don't want to tell anyone though we're doing this FET because if it doesn't work then I will go on the trip and drink my ass off ;) There are enough people going and everyone knows each other so it won't be a big deal if they all book everything and then I can't go but I just feel like I'm keeping such a secret. I told the lady tonight that I might not have money to buy my plane tickets until April (aka know if I'm pregnant or not). When we get home from Vegas I am going to Cozumel the next week so if this FET doesn't work I will definitely have plenty of opportunity to drink away my sorrows.
