TMI- need suggestions

So this pregnancy is completely different than my last. I'm literally going between having diarrhea and being constipated. I've been doing this since 6 weeks and I'll be 9 weeks tomorrow. OB I saw yesterday said that it can be normal, but offered no suggestions on what to do to help. I didn't vibe with the ob and will be looking for another, but in the meantime, can anyone suggest something to help? I'm drinking plenty and get good fiber in my diet.

My stomach and bum thank you in advance
