I went to the doctor yesterday and he did a sonogram and said amniotic fluid was a little low and he checked my cervix and I'm 1cm dilated and 75% effaced and babys head was -2 station so he did a membrane sweep and I've been having contractions and cramping along with back pain and pressure and sharp stinging pain in my vagina and this morning I vomited and I've been nauseated all day and like an hour ago I had diarrhea do you think I'm about to have her??
