I haven't gotten my UC/CSU acceptance letters yet? what is happening?

i am a transfer student. and its already mid-may, but, i haven't gotten anything from UC acceptance letter yet. i applied at the right time and sent everything i needed to. i only heard from LA, Irvine, and Davis, but other UC schools arent sending me anything, they are not sending me any email or mail. does it mean i didn't get accepted???? i am so worried.....
