Introduction
Frequent contractions at 37 weeks without pain may be due to increased sensitivity of the uterine muscle layer, false labor contractions (Braxton Hicks contractions), or insufficient contraction intensity. Specifically, in late pregnancy, the uterus enlarges, which increases the sensitivity of the uterine muscle layer and consequently heightens overall bodily sensitivity. This can lead to frequent contractions at 37 weeks that are not painful.

Frequent contractions at 37 weeks without pain may be due to increased sensitivity of the uterine muscle layer, false labor contractions (Braxton Hicks), or insufficient contraction intensity. The details are as follows:

1. Increased Sensitivity of the Uterine Muscle Layer

In late pregnancy, the uterus enlarges, which increases the sensitivity of the uterine muscle layer and consequently heightens overall bodily sensitivity. This can lead to frequent but painless contractions at 37 weeks. It is recommended that pregnant women rest in a lateral position to help the body feel more comfortable.

2. False Labor Contractions (Braxton Hicks)

At 37 weeks of pregnancy, as the uterus grows larger, the fetal head descends and exerts pressure on the pelvic bones, leading to false labor contractions. In such cases, no special treatment is usually required—adequate rest is sufficient.

3. Insufficient Contraction Intensity

At 37 weeks, which is considered late pregnancy, delivery is approaching, so mild contractions may begin to occur. Since contractions typically progress from mild to strong, frequent but painless contractions may indicate that the contractions are not yet strong enough. In this case, it is advisable to go to the hospital promptly to avoid delaying normal labor.
