Constant bubble guts

Hi everyone, I (30F) have dealt with digestion problems for years. Long story short I was going to a GI and it was a waste of time, money and stress because they just kept having me take expensive tests and give me prescriptions that my insurance company wouldn’t cover. So finally my husband was like try a probiotic and it helped, until it didn’t.

I read somewhere that you should switch probiotics every 30 days (most are 30 day supplies), so that’s what I do but I’m starting to wonder if I created a gut irritation by doing that.

I’m ALWAYS bloated now. I’ve been asked before if I’m pregnant. I’m a thin/average body type but I’m so bloated all the time I look pregnant! Literally anything I eat gives me the bubble guts and it’s all trapped. Mostly protein meals but I would say almost anything.

I recently found out I have “PCOS appearing ovaries”, but all my hormone levels were normal, but I feel like the bloating has gotten worse the last maybe 2 months…

What should I do? I don’t really want to go to the GI considering they didn’t help me at all.
