UC doesn't "turn into" Crohn's, or vice versa, but it can be misdiagnosed. Around 10-15% of IBD is indeterminate, i.e. can't be classified as Crohn's or UC. Sometimes indeterminate colitis is identified as Crohn's or UC later on, but not always.
Small bowel disease eliminates UC, but the only way to find out if you have that is to have tests done. You can't go by symptoms alone.
