When Should You Go to the Hospital for Labor?

By trimester

Weeks 1–13

1st trimester

The 5-1-1 rule does not apply to first-trimester pain or bleeding. Severe pain, heavy bleeding, fainting, shoulder pain, or concerning symptoms need urgent assessment based on gestational age and the care team’s instructions.

Weeks 14–27

2nd trimester

Regular or frequent contractions before 37 weeks, fluid leakage, bleeding, pelvic pressure, or a persistent low backache need an immediate call to the obstetric team or hospital assessment. Do not wait for a term-labor contraction pattern.

Weeks 28–birth

3rd trimester

In the third trimester, time contractions from the start of one to the start of the next and follow the labor unit’s instructions. Prior fast birth, long travel, twins, a high-risk condition, or a planned cesarean can change when the team wants contact or arrival.

What does the evidence show for when to go to the hospital for labor?

• NICHD describes true labor contractions as regular, increasingly close, lasting about 30 to 70 seconds, strengthening over time, and continuing with movement. These features help distinguish labor but do not supply a universal hospital-admission threshold. 1
• An NCBI nursing text says true contractions become regular, closer, and stronger and do not resolve with rest or position changes; it describes calling when contractions are regular, about five to seven minutes apart, and last 30 to 70 seconds. 2
• The current NICE intrapartum guideline directs anyone with suspected ruptured membranes at term to contact the maternity unit for phone triage and calls for urgent in-person review when fluid is accompanied by bleeding, reduced fetal movement, continuous pain, abnormal color or odor, or feeling unwell. 3
• ACOG advises calling the obstetric clinician right away or going to the hospital for possible preterm-labor symptoms before 37 weeks, including frequent contractions, pelvic pressure, persistent low backache, changes in discharge, or fluid leakage. A five-minute contraction pattern is not a prerequisite. 4
• The NCBI Braxton Hicks reference advises immediate clinician contact for vaginal bleeding, vaginal fluid leakage, contractions too strong to walk through, or strong contractions every five minutes for an hour. It does not establish one-minute duration or make 5-1-1 a universal admission rule. 5

When should I call my provider about when to go to the hospital for labor?

Call the labor unit right away for suspected ruptured membranes, reduced fetal movement, bright-red or heavy vaginal bleeding, continuous abdominal pain, abnormal-colored or foul-smelling fluid, or feeling unwell. Before 37 weeks, frequent contractions, pelvic pressure, a persistent low backache, or fluid leakage also require immediate contact or hospital assessment. A 5-1-1 pattern never overrides your obstetric team's instructions. Whatever the pattern, any symptom that feels beyond your usual range is a reason to call: obstetric teams expect these questions and would rather hear early than late.
