Most of the time wobbles happen when the snake is stressed, so your snake could be stressed. If it settles in and calms down I'm sure it wouldn't happen again unless it's stressed. Sometimes it could happen at random times when the snake isn't stressed at all either, so most likely your snake just has the wobble, luckily. IBD would be horrible, and each time I purchase a python or boa I fear the IBD because I definitely wouldn't want it spreading to Candice, that would just be insanely heart breaking to me.
