Infections of the urinary tract, vagina, cervix, etc. This is not an all-inclusive list. If you have questions about these conditions, discuss them with your doctor. Being at an increased risk does not mean a woman will have a preterm baby. It is possible to prevent a baby from being born too early, in some cases, if early warning signs are recognized and steps are taken to stop labor.
Contractions come closer together as time goes on.
Menstrual-like cramps come and go or don't go away. Pressure in your pelvis, back, or insides of your thighs. It feels like the baby is pushing down. Dull backache below your waist comes and goes or doesn't go away. Do not lie flat on your back.
