Help, I need tips!

Sorry if this is TMI but my doctor hasn’t given me any advice to help me out. I am currently 24 weeks and 5 days today, and I have terrible diarrhea. When I first found out I was pregnant, I lost around 7 pounds from having diarrhea. My only problem is I have irritable bowel syndrome and I also have had my gallbladder removed. I have really changed my diet and I avoid food I know gives me diarrhea but now I get it first thing in the morning, even if I haven’t ate anything. I have only gained 4 pounds my whole pregnancy so far because of this. Does anyone have any advice or tips to help??
