I WANT TO TURN UP ON MY BIRTHDAY TOMORROW!!!

Okay so my 25th birthday is tomorrow yayyy!!! And I can't lie I want to drink really bad and enjoy myself but I don't want to take the risk I'm in my tww and I don't know if I conceived a baby or not and that is very important to me...so I kinda want to drink something light and not get wasted...do you ladies think thats a good idea or no???
