I've been in a similar position to this as not being told what happens next however I had already enquired about it.
Basically, if you're willing to take a full time post when you finish your internship then just ask.
DON'T directly ask for a job, just say something along the lines of (can be adjusted to suit you)
Hey "x", I've been wondering recently as it's coming to the end of my college year what my future here holds. Will I be potentially be getting kept on and if no what will happen to my work, do I just leave it at a point to pass it on?
This makes it seem you haven't already assumed you're getting the job but you're also willing to prepare your work for the next person (if need be). Also shows that you're being prepared so it may or may not add to your credibility when potentially securing the full time post.
is it too early to ask
Not at all, in fact theres not long left at all now would be perfect timing to do so as you'll be leaving yourself ample time to apply for a new job elsewhere should the answer to your question be negative. As well as this if the answer is no - it's not all bad, you'll still have an internship when applying for jobs which will help you in the long run when applying for other jobs as explained Here
