Question I am 33 weeks today, I know this is tmi but I have had diarrhea for 3 days now. I have had super nausea today after I eat any thing. I don't remember any of this with my older daughter (5) I am just wondering if it's early signs of labor or if it just getting sick. I feel fine otherwise. I had a c-section with my daughter never had labor start or even try to. Any advice would be great thanks in advance
