Labor is characterized by RHYTHMIC contractions. It is common to confuse the onset of true labor with false labor, which presents as painful but irregular contractions. There is no labor without RHYTHMIC contractions.
Labor generally begins after the 37th week of pregnancy. Several signs, described below, may indicate its approach:
- Loss of the mucous plug: a gelatinous mucus tinged with blood, indicating changes in the cervix. This may occur days or even weeks before labor begins.
- Abdominal tightening or contractions that become increasingly regular and painful. True labor is considered when there are at least two contractions every ten minutes, each lasting about 45 seconds. Smartphone apps can help count contractions.
- Cervical changes: the cervix becomes progressively thinner (effaced) and more dilated — assessed by a physician or midwife.
- Rupture of membranes (water breaking): amniotic fluid may leak continuously or gush out. Note: amniotic fluid is clear and odorless, unlike urine.
What to do?
Contact your obstetrician when contractions become regular (at least 2 every 10 minutes), if your membranes rupture, or if there is heavy bleeding.
If this is your first pregnancy, you generally have more time before going to the hospital or birth center. If it is not your first, act more quickly as labor may progress faster.
When in doubt, always contact your doctor. Every pregnancy is unique and only your healthcare provider can give personalized guidance.
