Mucus in stool 34 weeks??

So I have had diarrhea for 5 weeks now. TMI I’m sorry😅. My ob says it’s normal so I’ve just been trying to stick to a bland diet. But now I notice that I have a lot of mucus mixed in with it when I go to the bathroom. Is this normal? I’m going to ask tomorrow at my appointment but I feel like I’m always asking so many questions so just wanted to see what you guys thought about it first.
