Soy formula mommies!!!! 🚨

Can soy cause horrible gas and fussiness instead of preventing it? I’ve noticed ever since a month of so if my daughters pediatrician switching her to soy formula because she wasn’t usually the bathroom regularly she has horrible gas especially at night where no one really gets any sleep, warm bottles and gas drops do not work! I’m starting to think it’s the soy formula!???? My pediatrician is switching my LO back to Similac total comfort. I’m just so nervous she’s got some serious belly issues if the soy made her belly worse is this possible?
