Soy can be very gassy and cause bloating for lots of us. Soy is a bean and maybe your body just doesn't like soy. Just a thought.
I don't eat soy, but I'm still bloated and gassy. And like Linz said, if you are C, I would get some IF in now. C takes so much longer to mangage.
Also, oatmeal can be a problem for some people. Why not try cream of rice or malt o meal or cooked quinoa flakes as an alternative hot cereal for a few days. Or try eating the instant oatmeal which some people find easier to digest than the oatmeal.
It could also be the introduction of so many carbs without eating other sources of foods, like protein and veggies. I personally think carbs are gas and bloat producers. Even though they serve as excellent SF.
Are you taking an SFS? Maybe the one you chose is not agreeing with you?
