Hey girls, has anyone had loose stools for a long time? Is that normal? I've been having this for four days now. Although I take sorbifer, they say it should be constipation. I'm worried about it and there was some nausea yesterday. It's hard to sleep already, even though I'm 37 weeks pregnant. I see everyone practically goes until 40.
