Re: Worried about the bloating?
If you're worried about OC, esp. if there is family history, see your OBGYN & get checked. Tho' in my mind, if this is a come & go problem as you suggest, it's more likely to be gut-related.
When that checks out, if you want to pursue the bloating, there are several different things to try:
1) Consume a probiotic regularly for several weeks & see if that helps. Sometimes bloating is caused by "bad bugs" displacing the good guys in the gut. A few weeks of yogurt w/active cultures, or of a probiotic supplement, can reduce or eliminate the problem if simple gut dysbiosis is to blame.
2) Get a referral to a GI doc (gastroenterologist) for further eval.
3) Consider the possibility that food intolerances or allergies are playing a role. Bloating is very common in lactose intolerance, gluten intolerance,and disaccharide intolerance. There are various forms of testing, some accepted by conventional MDs, others not, but LOTS of people who've found help by getting on top of their intolerances.
