What do to after signing the Navy contract and taken the oath?

i just signed the Navy contract and has taken the oath last week and they told me that im officially in the Navy and all that stuff but i did my research and found out that im not in the Navy officially until i take my final oath the day before i leave for bootcamp.. and after thinking hard about it i realized that i dont wanna go Navy anymore and im 100% sure about it.. but the problem is in 1 1/2 i need to go my recruiter and he told me that he's gonna orient and tell me about the contract for an hour.. what do i do? i dont want to go to navy anymore and i dont want to go to the navy office anymore.. should i just pretend that im still interested in going to the Navy and then just dont show up on the day before i leave for bootcamp? bec i read that it's gonna be much more problematic if tell them i want to quit right now.. pls help!! thanks
