Bloating problems on and off weeks??

I've been seeing a gastroenterologist and trying to figure out a diagnosis since I kind of self diagnosed myself with IBS. I have had stomach problems for a couple years now but it's gotten worse the past month or so. Now I've reached my breaking point

Does anyone else experience on and off weeks of bloating where literally anything you eat causes bloating and constipation? I have some good weeks where I feel fine and can eat normally, then a week or two of those issues. I can't figure out trigger foods because it feels like it's literally everything and anything to the point I would rather not eat (😬). The constipated feeling drives me nuts also. I can all feel it in my lower abdomen and just feels like sharp gas pains. I have no idea anymore and I'm so sick of it...
