What it says as in signs. Low, dull backache. Four or more
uterine contractions per hour.
Contractions may feel like; menstrual cramps, sensation of baby rolling up, increased uterine activity, abdominal cramping (with out without diarrhea) , and increased pelvic pressure (with or without thigh cramps).
Thats all word for word from my book.
It says if you experience any of these symptoms, lie down on your side, place a hand on your lower abdomen and feel for contractions.
