GI issues still? 14 weeks

This is not a pretty topic so my apologies but I have had consistent, daily diarrhea since 6 weeks and am now 14 weeks. Sometimes it’s just mostly mucus. I generally eat pretty clean and am limiting dairy but my stomach gets so upset no matter what or how much/little I eat - the growling is so intense it sounds like a monster’s in it. I have terrible gas every time I go to the bathroom. I feel so gross and am so sick of this constant upset stomach. Unfortunately my OB isn’t much help with a wait and see method and simply encouraging me to avoid dehydration.

Has anyone else experienced this/any suggestions?
