Really need to ask this.

I’m pregnant... 14 weeks 3 days. I have diarrhea everyday. But then again I do have microscopic colitis in my intestines and IBS. I’m on pills for it. And I can’t seem to eat anything without shitting my brains out. But is it possible to have diarrhea and constipation? I can go but then I have to sit there a minute because it feels like I still have to go and then I do go but a few minutes after and I have to push a bit. Is this normal? Any advice for it?
