I am leaving for army bct in 2 weeks, can i change my mos?

Im in the dep program and i leave in 2 weeks. I want to be in the army for a minimum of 2 years and a maximum of 4 years. I signed up to be a 68 whiskey (healthcare specialist) and ive always wanted to be in the medical field so if i cant change my mos it wont discourage me in anyway but thinking things over i found out i also have a deep interest in the intelligence field. Is it still possible to change my mos? especially since i only have 2 weeks remaining? Also id like a job that deals with intelligence gathering of some sort so could anyone give me some ideas if i can switch?
