The girls are pregnant at 13 weeks. Since week 10 there were threats then they said hypertonus of the uterus, prescribed candles, there were brown discharge. Still pulling down the lower abdomen and colic, some kind of constipation is very painful. Has anyone had this? What helps you say please. Is it normal for this tonus, is it not dangerous that I should do in such cases?
