Yup, with both of my pregnancies so far I have had diarrhea. With the first I had no nausea along with it, whereas this time I have moderate to severe nausea most of the day. But yes, definitely diarrhea. It's mostly cleared up at this point (7.5 weeks), but I still have it some days. The first time it was gone by the end of the first trimester, but I barely had any of the typical pregnancy constipation, which was a blessing!
