The signs of preterm labor, which occurs when regular contractions result in the opening of the cervix after week 20 and before week 37 of pregnancy, include:
- Regular or frequent sensations of abdominal tightening (contractions)
- Constant low, dull backache
- A sensation of pelvic or lower abdominal pressure
- Mild abdominal cramps
- Vaginal spotting or light bleeding
- Preterm rupture of membranes — in a gush or a continuous trickle of fluid after the membrane around the baby breaks or tears
- A change in the type of vaginal discharge — watery, mucus-like, or bloody
If you experience these signs or symptoms or you’re concerned about what you’re feeling, it’s important to contact your healthcare provider right away. It’s always better to be safe and get checked, even if it turns out to be a false alarm.
Preterm labor can affect any pregnancy, and while certain risk factors might increase the chance of preterm labor, it can also occur in pregnant women with no known risk factors.
