Hi, I just recently took at EARLY detection pregnancy test, and too my surprise I am 3 weeks 5 days pregnant..but since I have found out, I have a few episodes of diarrhea a day..only cramp when I have to run to the bathroom..I'll use it and then I am fine. I am fatigued, but this is my 3rd pregnancy I am always tired the first trimester...worried about a possible miscarriage...diarrhea normal early in pregnancy?
