I have diarrhea but no cramps or vomiting, both parents have ibs so maybe it is that?

Too early: Hollie, it is to early to make any assumption. Usually, based on duration of the symptoms we decide if it' s an acute or chronic condition. For you it will be critical to keep a log of your symptoms, what' s making it better or worse and so on. IBS is always a possibility, but it is a poorly understood clinical condition for which we do not have curative treatment.
