Is diarrhea a sign of pregnancy or miscarriage?

Answer

no

---

I think it possibly could be a sign. My baby stopped growing 6w2d and my diarrhea started that day, but I did not miscarry for 3 weeks. Once the baby stopped growing, I had diarrhea for 7 days straight - and that never happens to me.

Now I am pregnant again & I hit 6w2d yesterday and my diarrhea started again. The doctors feel my baby will not make it based on my 6w1d ultrasound, so this diarrhea could be a sign in my 2nd miscarriage.
